Question

Ratio of nidhis age 3 years hence to riddhis age 5 years agobis 5:2 and sum of their present age is 44 then find thr differebce between present age

Answer 1

Let age of Nidhi be x

Age of Ridhi be y

x+3/y-5= 5/2

2x+6= 5y-25

2x= 5y-31

x= 5y-31/2

x+y= 44

5y-31/2 +y =44

5y-31 +2y= 88

7y= 88+31

7y= 119

y= 17 years

x= 27 years

Difference between ages = x-y= 10 years
