5 years ago Amith was three times as old as his daughter and 10 years hence, he will be two times as old as his daughter. Then Amith’s current age is, Choose the correct choice from the following answers
A) 10
B) 50
C) 40
D) 20
E) 60
D   20   Amith’s age = A and   daughter’s age =B   Then, A – 5 = 3(B – 5)   =&gt; A – 3B + 10 = 0 ……(1)   And, A + 10 = 2 (A + 10)   =&gt; A – 2B – 10 = 0 ……(2)   Solving the 2 eqns, we will get   A = 50, B = 20.   Therefore,   Amith’s age is 50   And his 20aughter’s age is 20
