Question

John is 2 years older than Ify. In 6 years time Ify's age will be 4/5 of John's age. Find their ages

Answer 1

Explanation:

j = i + 2 now add 6 years to ech of their ages

4/5 ( j+6) = i + 6 sub in the first equation for j

4/5 ( i+2 + 6) = i + 6

4/5 i + 32/5 = i + 6

2/5 = 1/5 i

i = 2 then j = 4 y/o
