What is it about and what does it do
Answer:
Hari is 20; Harry is 28
Step-by-step explanation:
The ratio in 4 years is equivalent to the ratio 6:8, which has each of the original ratio unit numbers increased by 1. That means each of those ratio units stands for 4 years, and the present ages are ...
Hari: 5·4 = 20
Harry: 7·4 = 28
_____
<em>Conventional method of solution</em>
If you like, you can write equations for the ages of Hari (x) and Harry (y):
x/y = 5/7
(x+4)/(y+4) = 3/4
These can be solved a variety of ways. For some methods, it may be useful to write them in standard form:
These have solution (x, y) = (20, 28).
