# What will be Daisy’s age ?

The ratio between the present ages of Daisy and Rosy is 2:3 respectively. Four years ago, the ratio between their ages was 5:8 respectively. What will be Daisy’s age after 7 years:

- 29 years
- 30 years
- 31 years
- None of these

**Answer: (3) 31 years**

**Explanation:-**

The ratio between the present ages of Daisy and Rosy is 2:3.

Let the present age of Daisy = 2 X & the present age of Rosy = 3 X.

According to the question,

(2 X – 4)/(3 X – 4) = 5/8

8 (2 X – 4) = 5 (3 X – 4) (by cross multiplication)

16 X – 32 = 15 X – 20

16 X – 15 X = – 20 + 32

X = 12

Then, the present age of Daisy 2 X = 2 x 12

= 24 years

Therefore, the age of Daisy after 7 years = 24 + 7

= 31 years.

Hence, the answer is (3) 31 years.
