Question

the sum of present age of Ruchi and age after 7 years is 41 find the present age of Ruchi and her age before 7 years​

Answer 1

Let present age be X years
Age after 7 years = X + 7
Sum of ages = 41
X + (X+7) = 41
2 X = 41 - 7 = 34
X = 34/2 = 17
Present age = 17 years
Age after 7 years = 24 years

Answer 2

Answer:

we will make an equation

let her current age be x

x + x + 7 = 41

2x + 7 = 41

2x = 41 - 7 ( sign changes due to transposing )

2x = 34

x = 34/2 ( sign changes due to transposing )

x = 17

age before 7 years = 17 -7

                              = 10
