Question

The ages of reena and tina are in the ratio 3:4.Five years ago their ages were in the ratio2:3.Find their present ages?

Answer 1

Let the present ages of reena and tina are3x and 4x
Five years ago there ages were2:3
A/q
3x -5/ 4x-5 =2/3
9x -15= 8x-10
9x-8x =-10 + 15
x = 5
the present age of reena is 3×5 = 15 years.
the present age of tina is 4× 5= 20
