### Question 2

A 400 liter mixture of milk and water contains 86% milk. How many more liters of water should be added so that the proportions of milk and water become equal?

**A**

288 liter.

**B**

289 liter.

**C**

287 liter.

**D**

291 liter.

**Soln.**

**Ans: a**

The volume of milk will remain same at ${86 × 400}/100$ = 344 liters. The amount of water at present is 400 - 344 = 56 liters. We need to make the volume of water equal to that of the milk. So we have to add 344 - 56 = 288 liters of water.

### Question 5

A bag contains 25p, 10p and 5p coins in the ratio 2 : 13 : 12. How many 25 paise coins are there if the total amount is Rs. 48?

**A**

40.

**B**

42.

**C**

38.

**D**

44.

**Soln.**

**Ans: a**

Let the total number of coins be 2x, 13x and 12x. Please note that 25p = Rs. 1/4, 10p = Rs. 1/10, 5p = Rs. 1/20, so they add to x × $(2/4 + 13/10 + 12/20)$ = 48. LCM of 4, 10 and 20 is 20, multiplying both sides by 20 we have x × $(2 × 5 + 13 × 2 + 12)$ = 48 × 20, which is x × $(10 + 26 + 12)$ = 48 × 20, solving for x we get x = 20, so 25p coins = 20 × 2 = 40.
