Answer 2

Answer:

The difference in their ages = 4 years

Step-by-step explanation:

The ages of Shirish and Kunder are in the ratio of 5:6 respectively. After 8 years the ratio of their ages will be 7:8.

Step 1

Let the present ages of Shirish and Kunder be 5x and 6 years respectively.

Let, the ratio of their ages after 8 years

$= \frac{5x+8}{6x+8}$

$=\frac{7}{8}$

Step 2

Simplifying the above equation, we get

$&\Rightarrow 40 x+64=42 x+56$

$&44 x-40 x=64-56$

$&\Rightarrow 2 x=8$

$&\Rightarrow x=\frac{8}{2}=4$

Differences in their ages $=6 x-5 x=x$

= 4 years

Therefore, the difference in their ages = 4 years.
