The difference in present ages of Giri and Hari is 6 years
Given :
- The ratio of the present age of Giri and Hari is 5 : 8
- 12 years hence, the ratio of their ages will be 11 : 14
To find :
The difference in present ages of Giri and Hari
Solution :
Step 1 of 3 :
Form the equation to calculate present ages of Giri and Hari
Here it is given ratio of the present age of Giri and Hari is 5 : 8
Let present ages of Giri and Hari are 5x years and 8x years respectively
12 years hence ages of Giri and Hari will be (5x + 12) years and (8x + 12) years respectively
So by the given condition
Step 2 of 3 :
Calculate present ages of Giri and Hari
Giri's present age
= 5x years
= (5 × 2) years
= 10 years
Hari's present age
= 8x years
= (8 × 2) years
= 16 years
Step 3 of 3 :
Calculate difference in present ages of Giri and Hari
Giri's present age = 10 years
Hari's present age = 16 years
Hence difference in present ages of Giri and Hari
= 16 years - 10 years
= 6 years
