Question

The sum of ages of Mohit and his father is 45
years. If 9 is added to three times the age of
Mohit, the sum is equal to the present age of
his father. What is Mohit's present age?

​

Answer 1

Answer:

mohit's present age is 9

Step-by-step explanation:

let mohit's age be x

mohit's father's age = 3x + 9

sum of mohit's age and father's age = 45

so,

x + 3x + 9 = 45

4x + 9 = 45

4x = 45 - 9

4x = 36

x = 36/4

x = 9

let us check if our answer is right

mohit's age = x = 9

father's age = 3x + 9

                    = 3 x 9 + 9

                    = 27 + 9

                    = 36

sum of mohit's age and father's age = 45

36 + 9 = 45

so our answer is right

therefore, mohit's present age is 9

Answer 2

Answer:

36

Step-by-step explanation:

x+x=45

9+3x+x=45

3x+x=45-9

4x=36

x=36/4

x=9

Therefore : Mohit's present age =

9+3x

9+(3*9)

9+27

Your final answer is

36
