Question

shipra,s age is three times sona,s age and the difference of their age is 20 years find their age

Answer 1

Let the age of Sona be x
Age of Shipra = 3x
ATQ -
3x-x = 20
2x = 20
x = 20/2
x = 10
so Sona's age is 10 years and Shipra's age is 3*10 = 30 years

Answer 2

Let sona's age be x years
So Shipra's age will be 3x years... Because here age is three times..
According to question,
Difference in age is 20
Therefore, 3x-x=20
2x=20
x=20/2
x=10

Therefore sona's age is 10 years.
And Shipra's age is ( 3*10 ) years, which is equal to 30 years...
