Question

The of the shorter piece.

6 Jameelah is exactly 8 years older than Anna.
The ratio of their ages is 9:7.
How old is Anna?​

Answer 1

28

Explanation:

Let us take , age of Anna be x , then the age of Jameelah = x + 8 . Also the ratio of ages is 9:7 . So ,

According to the Question :-

`:\implies` x + 8/x = 9/7

`:\implies` 7( x + 8) = 9x

`:\implies` 7x + 56 = 9x

`:\implies` 9x - 7x = 56

`:\implies` 2x = 56

`:\implies` x = 28

Hence the age of Anna is 28 years .

Answer 2

28

Explanation:

the ratio of their ages is 9 : 7 = 9x : 7x ( x is a multiplier ) , then

9x = 7x + 8 ( Jameelah is 8 years older than Anna )

Subtract 7x from both sides

2x = 8 ( divide both sides by 2 )

x = 4 , then

7x = 7 × 4 = 28

That is Anna is 28
