are their present ages?
​

Answer 1

Answer:

The ages of Navneet and Harish are in the ratio 5:7

Let Rahul’s present age=5x

Haroon present age=7x

Four years later the sum of their ages will be 56 years. So according to the condition,

(5x+4)+(7x+4)=56

12x+8=56

12x=56–8

12x=48

x=48/12

x=4

Therefore Navneet’s present age =5*4=20years

Harish’s present age=7*4=28years

Answer 2

let the present age of Navneet be 5x and Harish be 7x

Age of Navneet after4year =5x+4

Age of Harish after4year =7x+4

5x+4+7x+4=56

5x+7x+4+4=56

12x+8=56

12x=56-8

x=48/12

x=4

Therefore, present age of Navneet is 5 × 4 is = 20

Present age of Harish is7×4=28
