Let Sarita's age be 2x and Anushka's be x.
=> According to the question:
=> 4(x-6) = 2x+4
=> 4x-24 = 2x+4
=> 4x-2x = 4+24
=> 2x = 28
=> x = 28/2 = 14
=> Anushka's present age = 14
=> Sarita's present age = 2x = 2*14 = 28
THEREFORE:
=> Anushka's age 2 years back = 14-2 = 12
=> Sarita's age 2 years back = 28-2 = 26
=> According to the question:
=> 4(x-6) = 2x+4
=> 4x-24 = 2x+4
=> 4x-2x = 4+24
=> 2x = 28
=> x = 28/2 = 14
=> Anushka's present age = 14
=> Sarita's present age = 2x = 2*14 = 28
THEREFORE:
=> Anushka's age 2 years back = 14-2 = 12
=> Sarita's age 2 years back = 28-2 = 26
