The sum of present ages Ria and Abi is 48 years. Today Abi is 4 years older than Shweta. The respective ratio of the present ages of Ria and Shweta is 4:7. what was Abi’s age two years ago?

R + A = 48 —(1)
A = S + 4 –(2)
R/S = 4/7
R + S + 4 = 48 => R + S = 44

x = 4
Shweta’s age = 28
Abi’s present age = 28 + 4 = 32
