SBI Clerk Mains Mixture & Alligation Practice Questions

1. Rohan purchases 160 litres of milk at Rs. 5 per litre, and mixes 80 litres of water (free of cost) in it. He sells some amount of mixture at Rs. 5 per litre in which quantity of water is 30 litres, and again he mixes ‘x’ litres of water in it. If he sells the remaining mixture at Rs. 4 per litre, and profit earned by him is Rs. 330, then find the value of ‘x’.

a. 30

b. 15

c. 20

d. 40

e. 35

Answer: c)

Solution:

Total cost price of milk = 160 × 5 = Rs. 800

Ratio of milk to water initially = 160:80 = 2:1

So, amount of mixture sold = 30/1 × 3 = 90 litres

Total amount sold = ‘240 + x’ litres

So, 90 × 5 + (150 + x) × 4 – 800 = 330

450 + 600 + 4x – 800 = 330

4x = 80, x = 20

Hence, option c.

1. A vessel contains 540 litres mixture of honey, milk and water in the ratio of 3:4:5 respectively. 15 litres of honey and 20 litres of milk is added to this mixture. Find the new ratio of honey, milk and water in the vessel.

a. 7:2:8

b. 2:3:5

c. 6:8:9

d. 4:5:3

e. 7:8:9

Answer: c)

Solution:

Quantity of honey in vessel initially = [3/ (3 + 4 + 5)] × 540 = 135 litres

Quantity of milk in vessel initially = [4/ (3 + 4 + 5)] × 540 = 180 litres

Quantity of water in vessel initially = [5/ (3 + 4 + 5)] × 540 = 225 litres

Therefore, required ratio = (135 + 15): (180 + 20): 225 = 150: 200: 225 = 6: 8: 9

Hence, option c.
