Question

Shraddha is 40 year old and 20 year old how many years ago was three times as old as sunita

Answer 1

Answer:

10 years

Step-by-step explanation:

let the no of years be 'x'

therefore, 40-x=3(20-x)

40-x=60-3x

(transposing)

40-60=-3x+x

-20=-2x

x=10

i.e, 10 years ago, Shraddha was three times as old as Sunita
