(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 questionsx + (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.
