### Question 1

Two numbers A and B are in ratio 14 : 15. If they are both increased by 10%, what will be the new ratio of A : B?

### Question 2

What is the value of the first part if 308 is divided in the ratio $7/3$ : $5/3$ : $8/9$?

### Question 3

A bag contains 25p, 10p and 5p coins in the ratio 6 : 9 : 11. How many 25 paise coins are there if the total amount is Rs. 59?

**A**

120.

**B**

122.

**C**

118.

**D**

124.

**Soln.**

**Ans: a**

Let the total number of coins be 6x, 9x and 11x. Please note that 25p = Rs. 1/4, 10p = Rs. 1/10, 5p = Rs. 1/20, so they add to x × $(6/4 + 9/10 + 11/20)$ = 59. LCM of 4, 10 and 20 is 20, multiplying both sides by 20 we have x × $(6 × 5 + 9 × 2 + 11)$ = 59 × 20, which is x × $(30 + 18 + 11)$ = 59 × 20, solving for x we get x = 20, so 25p coins = 20 × 6 = 120.

### Question 4

Two numbers M and N are in ratio 15 : 7. If they are, respectively, increased by 20% and 30%, what will be the new ratio of M : N?

### Question 5

If 10% of a number is equal to 4/13 of another number, then what is the ratio of first number to second number?

**A**

$3{1/13}$.

**B**

$4{5/12}$.

**C**

$1{4/5}$.

**D**

$5{4/15}$.

**Soln.**

**Ans: a**

We have ${10A}/100 = {4B}/13$, which can be re-arranged to $A/{4 × 100} = B/{10 × 13}$, so the required ratio is (4 × 100) : (10 × 13), which is 40 : 13. So the answer is ${40/13}$, which is same as: $3{1/13}$.
