Question

sharda is 40 year old and shamita is 20 years old .how many years ago was sharda three times old as Shanta. ​

Answer 1

Answer:

10

Step-by-step explanation:

Let Sharadha's age be x and Smita's age be y

x=40,y=20

let the number of years ago when Sharadha was three times as old as Smita be n.

(x-n)=3(y-n)

40-n=3(20-n)

40-n=60-3n

2n=20

n=10

Thus,10 years ago Sharadha was three times as old as Smita
