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

Step-by-step explanation:

lsuppose Ritu's age is R and her daughter's age is D

R - 2 = 3(D - 2)

R - 2 = 3D - 6

R = 3D - 4

2(R + 2) = 5(D + 2)

2R + 4 = 5D + 10

2R = 5D + 6

2(3D - 4) = 5D + 6

6D - 8 = 5D + 6

D = 14

R = 3*14-4

= 42-4

= 38

R + D = 38 + 14

= 52..
