Question

2 years ago reetu was three times as old as her daughter and two years hence twice her age will be equal to five times that of a daughter

Answer 1

suppose ,the age of reetu is X
and her daughter is Y

2 years ago she was X-2
she was 3× of her daughter

so , X-2 = 3 Y ..........1

2 years later reetu is X+2
and her daughter is 5× of her age

so , X+2 = 5Y...........2

from 1 and 2
X+2 = 3Y
X-2 = 5Y
...........................
2 X = 8 Y
or , X = 4 Y
or, X: Y= 4:1
