The questions asked in this section are calculative and very time-consuming. But once dealt with proper strategy, speed, and accuracy, this section can get you the maximum marks in the examination. Following is the Quantitative Aptitude quiz to help you practice with the best of latest pattern questions.

**Directions (1-5): The line graph below shows the profit made on selling a unit of mobile as a percent of selling price. The table shows the cost price of each brand of mobile sold by the shop ‘MOBILE WALA’.**

**Q1. If the total profit made by shop ‘Mobile Wala’ on selling mobiles of brand Vivo was Rs. 13,500, then find the number of units sold by the shop?**

9

11

10

8

15

Solution:

13500/SP = 20/100

⇒ SP = Rs. (13500 × 5)

Let, No. of units sold be ‘x’, then

6000 × x + 13500 = 13500 × 5

Or, 6000x = 4 × 13500

Or, x = 9

⇒ SP = Rs. (13500 × 5)

Let, No. of units sold be ‘x’, then

6000 × x + 13500 = 13500 × 5

Or, 6000x = 4 × 13500

Or, x = 9

**Q2. If shop ‘Mobile Wala’ sold 10 units of mobile of brand Samsung, then find the total selling price of all these 10 units sold and profit made on each unit.**

Required Ratio = 1 : 2

**Q6. In a bag there are three types of colored balls i.e, yellow, green and Red. The probability of getting one yellow ball is 2/5 and the probability of selecting one green ball is 3/7. If total number of Red balls are 18 then find the probability of selecting one red ball.**

6/35

7/26

4/35

2/35

8/35

Solution:

Let yellow balls = 2x

Then total balls = 5x

Let green balls = 3y

Then total balls = 7y

ATQ—

2x + 3y + 18 = 5x = 7y …(i)

From (i)

x – y = 6 ..(ii)

2y – x = 9 ….(iii)

Solving (ii) and (iii)

x = 21 and y = 15

Required probability = 18/105 = 6/35

Then total balls = 5x

Let green balls = 3y

Then total balls = 7y

ATQ—

2x + 3y + 18 = 5x = 7y …(i)

From (i)

x – y = 6 ..(ii)

2y – x = 9 ….(iii)

Solving (ii) and (iii)

x = 21 and y = 15

Required probability = 18/105 = 6/35

**Q7. There are 5 multiple choice questions in an examination. How many sequences of answers are possible, if the first three questions have 4 choices each and the next two have 6 choices each?**

2804

3456

7776

2304

1024

Solution:

Places: - - - - -

Digits: 4 4 4 6 6

Total number of sequences = 4 × 4 × 4 × 6 × 6 = 2304.

Digits: 4 4 4 6 6

Total number of sequences = 4 × 4 × 4 × 6 × 6 = 2304.

**Q8. A positive integer is selected at random and is divided by 11. Find the probability that the remainder is not an even number?**

3/11

8/11

5/11

9/11

7/11

Solution:

Total possible remainders = [0, 1, 2, 3, 4……..10]

Favorable remainders = [1, 3, 5, 7, 9]

Required probability = 5/11

Favorable remainders = [1, 3, 5, 7, 9]

Required probability = 5/11

? = 4116

×1+1, ×2+2, ×3+3, ×4+4, ×5+5, ×6+6

∴ ? = 685 ×6 + 6

? = 4116
