(e) Let’s assume age of father was A years and motherwasB. When Chari was born after x years of Hari the age ofHari = x years. According to questions x + (A + x) + (B + x) = 70 ...(i) When Gauri was born ftirther after 4 years. Then ages of 4 members (x + 4) + 4 (A+ x+ 4) + ( B + x+ 4) = 2 ( A+B) ⇒ 3x+ 16=A+B ....(ii) Fram (i)and(ii) ⇒3x+3x+ 16 = 70 ⇒x= 9 years.
