The ages of two friends Ani and Biju differ by 3 years . Ani' s father Dharam istwice as old as Ani and Biju is twice as old as his sister Cathy. The ages

of Cathy and Dharam differ by 30 years. Find the ages of Ani and Biju.

Let age of ani =a, biju=b, cathy =c, dharam =d. there are 2 cases, lets say Ani is elder than Biju , case 2 would be Biju is elder than Ani, Try that too, but lets take in case 1. a-b = 3 d=2a b=2c d-c=30 substituting (2a -b/2)2=30*2 a-b=3 now 4a - b = 60 - a - b = 3 3a = 57 a= 19, as biju is smaller than ani, b=16, d=2a, so d=38, c=b/2 so c=8years. You could take ani as smaller than biju, but u would get it wrong and dharam is father of ani , so will be bigger than biju and cathy. now d-c = 30, as 38-8= 30 so you may get it wrong on first attempt , but see to it that u try both cases.
