SBI PO 2019 Quantitative Aptitude Questions with Answers PDF Free Download

Directions: Read the following questions carefully and choose the right answer.
1
In 6 hours the distance covered by Chulbul is 6 km more than the distance covered by Bulbul in 7 hours. In 7 hours the distance covered by Chulbul is 3 km less than the distance covered by Bulbul in 9 hours. In a race of 180 km, by what distance will Chulbul beat Bulbul?
» Explain it
D
Let the speed of Chulbul = x km per hour and the speed of Bulbul = y km per hour

Distance = speed × time

6x – 7y = 6 ............ (i)

9y – 7x = 3 ......... (ii)

By solving, x = 15 km per hour and y = 12 km per hour

The time taken by Chulbul to cover 180 km =  180  = 12 hours
15

The distance travelled by Bulbul in 12 hour = 12 × 12 = 144 km

The distance by which Chulbul beats Bulbul = 180 – 144 = 36 km

Hence, option D is correct.
 
2
A mobile phone was sold at a profit of 20% on the cost price. If the mobile phone was sold at 10% lower than this price, then the profit would have been Rs. 600 less. At what price should the mobile phone be sold if one wants to gain 25% of the cost price?
» Explain it
C
Let CP = Rs. 100x, then

SP = 120% of 100x = Rs. 120x 
 
If the mobile phone was sold at 10% lower than this price then new SP

= (100 – 10)% of 120x

= 90% of 120x

= Rs. 108x 
 
According to the question,

120x – 108x

= 12x = 600
 
x = 50 
 
The CP = 100x = 100 × 50 = Rs. 5000 
 
The SP when one wants to gain 25% profit

= (100 + 25)% of 5000 = 125% of 5000

= Rs. 6250 
 
Hence, option C is correct.

 
3
Three friends A, B, C started working together on a piece of work. Once half of the work was completed B left the work and then A and C complete the remaining work together in 10 days. If B had worked with A and C together only for 6 days, then in how many days B alone can complete the piece of work?
» Explain it
C
B had worked for 6 days i.e. till half of work was completed it means, A, B, and C together can complete the half of the work in 6 days

Therefore, they together can complete the full work in 6 × 2 = 12 days

A and C together can complete the half of the work together in 10 days it means they together can complete the full work in 10 × 2 = 20 days

The number of days B alone will take to complete the work = x days then
 
1  =  1  –  1  =  2  =  1
x 12 20 60 30

x = 30 days

Hence, option C is correct.
4
The ratio of length to breadth of a rectangle is 1 : 2. If the length of the rectangle is increased by 20% and again it is decreased by 30% then the area of the rectangle is decreased by 32 sq. cm. What is the perimeter of the original rectangle?
» Explain it
A
Let the length of the rectangle = a cm then breadth = 2a cm 
 
The area of the rectangle = a × 2a sq. cm 
 
When length of increased by 20% then the new length = 120% of a = 1.2a 
 
Again, when it was decreased by 30% then the new length = (100 – 30)% of 1.2 a = 0.7 × 1.2a = 0.84a 
 
Area = 2a.× 0.84a = 1.68a2 
 
According to the question,

2a2 – 1.68a2 = 0.32a2 = 32 
 
a = 10  
 
The perimeter = 2(l + b) = 2 × (a + 2a) = 6a = 60 cm 

Hence, option A is correct.

8 years ago, the ratio of A’s age to B’s age was 4 : 5. At present the ratio of B’s age to C’s age is 4 : 5. At present, the difference between A’s age and C’s age is 20 years , then what is the sum of the ages of A , B and C ?
» Explain it
B
8 years ago, let A’s age = 4a years then B’s age = 5a years

At present, B’s age = 5a + 8 years = 4x

x =  5a + 8
4
Therefore, C’s age = 5x =  5 × (5a + 8)  =  25a + 40
4 4
According to the question,

25a + 40  – (4a + 8) = 20
4

25a + 40 – 16a – 32 = 80

9a = 72

a = 8 years

At present A, age = 4a + 8 = 40 years

B’s age = 5a + 8 = 48 years
 
C’s age =  5  × 48 = 60 years
4

The required sum = 40 + 48 + 60 = 148 years

Hence, option B is correct.
