Question

Rema is one seventh as old as her cousin. In 8 years she will be third as old as her cousin. There present ages are ?

Answer 1

Rama age = x
Her cousin age = y
X = (1/7)y
Y = 7x
X+8 = (1/3)(y+8)
3×(X+8) = y+8
3X + 24 = 7X + 8
4X = 16
X = 4
Y = 7X = 7×4 = 28
Present age of Rama = 12 years
Present age of her cousin = 36 years

Answer 2

Let her cusins age be x years Then age of reema will be x/7 years After 8 years cousin age cl be x+8 And reemas age vl be x/7+8 According to Q's.. After 8 years remmas age vl be 1/3 rd of cousin That means x/7+8= 1/3(x+8) X/7-x/3= 8/3-8 16/3=4x/21 X=28 Reema age vl be x/4 = 28/4= 7 years
