What is the difference between the total number of employees who left early and the total number of employees who left late?
» Explain it
A
The following common explanation, we get

 Early On time Late Arrived 5x (assume) 8y (assume) 4z (assume) Left X + 3y + z 2x + z + 2y 2x + 2z + 3y

the total number of employees who left early = X + 3Y + Z = 12 + 45 + 6 = 63

the total number of employees who left late = 2X + 2Z + 3Y = 24 + 12 + 45 = 81

The required difference = 81 – 63 = 18

Hence, option A is correct.

Common Explanation :

Let the number of employees who arrived early = 5x

The number of employees who left early = 20% of 5x = x

The number of employees who left late = 40% of 5x = 2x

The number of employees who left on time = 5x – 3x = 2x

Let the number of employees who arrived late at the office = 4z

The number of employees who left late = 50% of 4z = 2z

The number of employees who left on time 25% of 4z = z

The number of employees who left early = 4z – 3z = z

Let the number of employees who arrived on time = 8y

The number of employees who left early = 37.5% of 8y = 3y = The number of employees who left late

The number of employees who left on time = 8y – 6y = 2y

 Early On time Late Arrived 5x (assume) 8y (assume) 4z (assume) Left X + 3y + z 2x + z + 2y 2x + 2z + 3y

According to the question, 5x = 2x + z + 2y

3x = z + 2y ------- (i)

The number of employees who didn’t arrive on time = x + 3y + z + 2x + 2z + 3y = 144

3x + 3z + 6y = 144

From the equation (i), 9x = 3z + 6y ----- (ii)

Therefore, 3x + 9x = 12x = 144

X = 12

Again, according to the question, x + 3y + z = 4z + 39

3y – 3z = 27 ---------- (iii)

Adding equation (ii) and equation (iii)

9y = 9x + 27

Y = x + 3 = 12 + 3 = 15

From the equation (iii)

3z = 45 – 27 = 18

Z = 6
2
What is the total number of employees working in that branch?
» Explain it
C
The following common explanation, we get

the total number of employees working in that branch = 5x + 8y + 4z = 60 + 120 + 24 = 204

Hence, option C is correct.

Common Explanation :

Let the number of employees who arrived early = 5x

The number of employees who left early = 20% of 5x = x

The number of employees who left late = 40% of 5x = 2x

The number of employees who left on time = 5x – 3x = 2x

Let the number of employees who arrived late at the office = 4z

The number of employees who left late = 50% of 4z = 2z

The number of employees who left on time 25% of 4z = z

The number of employees who left early = 4z – 3z = z

Let the number of employees who arrived on time = 8y

The number of employees who left early = 37.5% of 8y = 3y = The number of employees who left late

The number of employees who left on time = 8y – 6y = 2y

 Early On time Late Arrived 5x (assume) 8y (assume) 4z (assume) Left X + 3y + z 2x + z + 2y 2x + 2z + 3y

According to the question, 5x = 2x + z + 2y

3x = z + 2y ------- (i)

The number of employees who didn’t arrive on time = x + 3y + z + 2x + 2z + 3y = 144

3x + 3z + 6y = 144

From the equation (i), 9x = 3z + 6y ----- (ii)

Therefore, 3x + 9x = 12x = 144

X = 12

Again, according to the question, x + 3y + z = 4z + 39

3y – 3z = 27 ---------- (iii)

Adding equation (ii) and equation (iii)

9y = 9x + 27

Y = x + 3 = 12 + 3 = 15

From the equation (iii)

3z = 45 – 27 = 18

Z = 6
3
Find the respective ratio of the number of employees who arrived early, the number of employees who arrived on time, and the number of employees who arrived late?
» Explain it
A
The following common explanation, we get

The respective ratio = 5x : 8y : 4z = 60 : 120 : 24 = 5 : 10 : 2

Hence, option A is correct.

Common Explanation :

Let the number of employees who arrived early = 5x

The number of employees who left early = 20% of 5x = x

The number of employees who left late = 40% of 5x = 2x

The number of employees who left on time = 5x – 3x = 2x

Let the number of employees who arrived late at the office = 4z

The number of employees who left late = 50% of 4z = 2z

The number of employees who left on time 25% of 4z = z

The number of employees who left early = 4z – 3z = z

Let the number of employees who arrived on time = 8y

The number of employees who left early = 37.5% of 8y = 3y = The number of employees who left late

The number of employees who left on time = 8y – 6y = 2y

 Early On time Late Arrived 5x (assume) 8y (assume) 4z (assume) Left X + 3y + z 2x + z + 2y 2x + 2z + 3y

According to the question, 5x = 2x + z + 2y

3x = z + 2y ------- (i)

The number of employees who didn’t arrive on time = x + 3y + z + 2x + 2z + 3y = 144

3x + 3z + 6y = 144

From the equation (i), 9x = 3z + 6y ----- (ii)

Therefore, 3x + 9x = 12x = 144

X = 12

Again, according to the question, x + 3y + z = 4z + 39

3y – 3z = 27 ---------- (iii)

Adding equation (ii) and equation (iii)

9y = 9x + 27

Y = x + 3 = 12 + 3 = 15

From the equation (iii)

3z = 45 – 27 = 18

Z = 6

Suppose on the day before yesterday of that day 25% of the total number of employees was on leave on the medical ground and 33.33% of the remaining was on leave for personal reason then how many employees was present on the day before yesterday of that day?
» Explain it
B
The following common explanation, we get

the total number of employees working in that branch = 5x + 8y + 4z = 60 + 120 + 24 = 204

of the total number of employees was on leave on the medical ground = 25% of 204 = 51

Remaining = 204 – 51 = 153

The number of employees who was on leave for personal reason = 33.33% of 153 = 51

The number of employees present on the day before yesterday of that day = 153 – 51 = 102

Hence, option B is correct.

Common Explanation :

Let the number of employees who arrived early = 5x

The number of employees who left early = 20% of 5x = x

The number of employees who left late = 40% of 5x = 2x

The number of employees who left on time = 5x – 3x = 2x

Let the number of employees who arrived late at the office = 4z

The number of employees who left late = 50% of 4z = 2z

The number of employees who left on time 25% of 4z = z

The number of employees who left early = 4z – 3z = z

Let the number of employees who arrived on time = 8y

The number of employees who left early = 37.5% of 8y = 3y = The number of employees who left late

The number of employees who left on time = 8y – 6y = 2y

 Early On time Late Arrived 5x (assume) 8y (assume) 4z (assume) Left X + 3y + z 2x + z + 2y 2x + 2z + 3y

According to the question, 5x = 2x + z + 2y

3x = z + 2y ------- (i)

The number of employees who didn’t arrive on time = x + 3y + z + 2x + 2z + 3y = 144

3x + 3z + 6y = 144

From the equation (i), 9x = 3z + 6y ----- (ii)

Therefore, 3x + 9x = 12x = 144

X = 12

Again, according to the question, x + 3y + z = 4z + 39

3y – 3z = 27 ---------- (iii)

Adding equation (ii) and equation (iii)

9y = 9x + 27

Y = x + 3 = 12 + 3 = 15

From the equation (iii)

3z = 45 – 27 = 18

Z = 6
5
The total number of employees who left on time was how much percent more than/less than the total number employees who didn’t leave on time?
» Explain it
C
The following common explanation, we get

The number of employees who left on time = 2x + z + 2y = 24 + 6 + 30 = 60

The number of employees who didn’t leave on time = x + 3y + z + 2x + 2z + 3y = 3x + 6y + 3z = 36 + 90 + 18 = 144

 The reqd. % = (144 – 60) × 100 = 84 × 100 = 58.33% approx. 144 144

Hence, option C is correct.

Common Explanation :

Let the number of employees who arrived early = 5x

The number of employees who left early = 20% of 5x = x

The number of employees who left late = 40% of 5x = 2x

The number of employees who left on time = 5x – 3x = 2x

Let the number of employees who arrived late at the office = 4z

The number of employees who left late = 50% of 4z = 2z

The number of employees who left on time 25% of 4z = z

The number of employees who left early = 4z – 3z = z

Let the number of employees who arrived on time = 8y

The number of employees who left early = 37.5% of 8y = 3y = The number of employees who left late

The number of employees who left on time = 8y – 6y = 2y

 Early On time Late Arrived 5x (assume) 8y (assume) 4z (assume) Left X + 3y + z 2x + z + 2y 2x + 2z + 3y

According to the question, 5x = 2x + z + 2y

3x = z + 2y ------- (i)

The number of employees who didn’t arrive on time = x + 3y + z + 2x + 2z + 3y = 144

3x + 3z + 6y = 144

From the equation (i), 9x = 3z + 6y ----- (ii)

Therefore, 3x + 9x = 12x = 144

X = 12

Again, according to the question, x + 3y + z = 4z + 39

3y – 3z = 27 ---------- (iii)

Adding equation (ii) and equation (iii)

9y = 9x + 27

Y = x + 3 = 12 + 3 = 15

From the equation (iii)

3z = 45 – 27 = 18

Z = 6
