Question

The difference between current age of Arun and Deepa is 14 years . 7 years ago the proportion of their age was 5: 7, respectively, what would be the current age of Deepa

Answer 1

Answer:56 years

Step-by-step explanation:

Let arun’s age be ‘x’

So deepa’s age is ‘x+14’

7 years ago their ages would have been :- ‘x-7’ and x+7’

Ratio of their ages was 5:7

So,

5:7::x-7:x+7

7(x-7)= 5(x+7)

7x-49=5x+35

2x=84

X=42

Deepa’s age= x+14=42+14=56.
