Question

The sum of present ages of Rohit and Mohit in 30 years. After 5 years the ratio of their present age will be 5:3. Find their present age.
​

Answer 1

Answer:

let one's age is x

other's age =30-x

a/q

x+5/(30-x)+5= 5/3

3x+15=35(5)-5x

8x=175-15

x=160/8

x=20

ages are 20 and 10

Answer 2

Answer:

Step-by-step explanation:

Let the age of Rohit be x .

Then, the age of Mohit = 30-x

After 5 years,

Age of Rohit = X+5

Age of Mohit = 30-x+5

ATQ

3(x+5)=5(30-x+5)

3(x-5)=5(35-x)

3x - 15 = 105 - 5x

8x = 120

Hence, X = 15 years

Rohit present age = 15years

Mohit present age = 30-15 = 15 years
