1
Two containers M and N contain mixture of petrol and diesel in the ratio of 3 : 1 and 7 : 3. The quantity of liquid in the container N is 40 litres more than the quantity of liquid in the container M and the total quantity in the 2 containers is 600 litres. What is the difference between the quantity of diesel in container M and N?
» Explain it
D
Let the quantity of liquid in container M and N be ‘m’ litres and ‘n’ litres respectively.

According to the question,

m + n = 600

Ans, n = m + 40

On solving, we get,

m = 280 litres and n = 320 litres respectively

 So, quantity of diesel in M = 1 × 280 = 70 litres 4

 Quantity of diesel in N = 3 × 320 = 96 litres 10

So, required difference = 96 – 70 = 26 litres

Hence, option D is correct.
2
R, S and T started a business by investing Rs. 40000, Rs. 60000 and Rs. ‘x’ respectively. At the end of 4 month, R contributed an additional capital equal to half of T’s initial capital. T left the business at the end of the 4th month while R and S invested for the whole year. If S’s share of 1st year profit of Rs. 9200 was Rs. 3600, find the value of x
» Explain it
B
Profit sharing ratio between R, S and T at the end of 1st year

 = [ 40000 × 4 + ( 40000 + x ) × 8 ] : [60000 × 12] : [x × 4] 2

= [480000 + 4x] :  : [4x]

S’s share of 1st year profit
 = 720000 × 9200 = 3600 480000 + 4x + 720000 + 4x

On solving, we get x = Rs. 80000

Hence, option B is correct.
3
A sum of money amounts to 12000 in 4 years and 9500 in 3 years under compound interest. What is the rate of interest per annum?
» Explain it
C
It is given that the under compound interest, a sum of money amounts to 12000 in 4 years and 9500 in 3 years.

So, percentage increase in value of money in 4th year from the 3rd year is :

 12000 – 9500 × 100 = 26.3% 9500

So, the rate of interest per annum = 26.3%

Hence, option C is correct.
4
A salesman has certain number of oranges of which 5% are found to be broken. He sells 93% of the remainder and still has 266 oranges left. How many oranges he originally had?
» Explain it
A
Let the total number of oranges be ‘x’

5% are found to be broken

Remaining = 95%

He sells 93% of the remaining, it means 7% of the remaining oranges are left, which is equal to 266 oranges

 So, 7 × 95 × x = 266 100 100

 x = 266 × 100 × 100 7 × 95

x = 4000

Hence, option A is correct.
5
When Chitra was born her mother’s age was 30 years and when her sister Bittu was born 4 years after her birth her father was 26 years old. Find the age difference between her parents?
» Explain it
E
Father’s age when Chitra’s brother was born = 26 years

Chitra’s brother was born 4 years after Chitra

Mother’s age when Chitra’s sister was born = Mother’s age when Chitra was born + 4

Mother’s age when Chitra’s sister was born = 30 + 4 = 34

Age difference between her parents = 34 – 26 = 8 years

Hence, option E is correct.

Q.1.  The area of lawn is 460 square metres. If the length is 15 percent more than the breadth of the rectangular field. What is the length of the field?

15 m
26 m
34.5 m
Can't be determined
None of these

Explanation:  Let, L and B are the length and breadth of the lawn

Length is 15% more than breadth

L = 1.15B

Area = L × B

460 = 1.15 B × B

B = 20 m

L = 23 m

Hence, option E is correct.
.
Q.2.  The average weight of 17 students is 90 kg. If the weight of teacher is also included, then the average weight is increased by 200 grams. Find the weight of the teacher?

94 kgs
93.6 kgs
93.4 kgs
94.6 kgs
None of these

Explanation:  Average weight of 17 students = 90 kg

Let, the weight of teacher be x

So, the average weight is increased by 200 grams

 Therefore, (17 × 90) + x = 90 + 200 18 1000

 1530 + x = 90.2 18

1530 + x = 1623.6

x = 1623.6 – 1530 = 93.6kgs

Therefore, the weight of the teacher = 93.6 kgs

Hence, option B is correct.

Q.3. If n is a natural number, then (12n2 + 12n) is always divisible by?

6 only
6 and 12 both
12 only
18 only
None of these

Explanation:  Given, (12n2 + 12n) = 12n (n + 1)

We know that  n (n + 1) will always be even

Therefore, (12n2 + 12n) will always be divisible by both 6 and 12

Hence, option B is correct.
