### Question 3

A bag contains 25p, 10p and 5p coins in the ratio 12 : 14 : 3. How many 25 paise coins are there if the total amount is Rs. 91?

**A**

240.

**B**

242.

**C**

238.

**D**

244.

**Soln.**

**Ans: a**

Let the total number of coins be 12x, 14x and 3x. Please note that 25p = Rs. 1/4, 10p = Rs. 1/10, 5p = Rs. 1/20, so they add to x × $(12/4 + 14/10 + 3/20)$ = 91. LCM of 4, 10 and 20 is 20, multiplying both sides by 20 we have x × $(12 × 5 + 14 × 2 + 3)$ = 91 × 20, which is x × $(60 + 28 + 3)$ = 91 × 20, solving for x we get x = 20, so 25p coins = 20 × 12 = 240.

### Question 4

Two numbers are in the ratio 19 : 9. If both are increased by 18, the new ratio becomes 52 : 27. What is the first number?

### Question 5

A 350 liter mixture of milk and water contains 62% milk. How many more liters of water should be added so that the proportions of milk and water become equal?

**A**

84 liter.

**B**

85 liter.

**C**

83 liter.

**D**

87 liter.

**Soln.**

**Ans: a**

The volume of milk will remain same at ${62 × 350}/100$ = 217 liters. The amount of water at present is 350 - 217 = 133 liters. We need to make the volume of water equal to that of the milk. So we have to add 217 - 133 = 84 liters of water.
