Question

Ria is 4 years elder to Rahul. After 10 years, the ratio of the ages of Rahul to Ria is 9:10. Find Rahul’s present age

Answer 1

Answer:

26 years

Step-by-step explanation:

Let Rahul's be x

Ria's age= 4+ x

Their age after 10 years = 4+x+10,x+10

A.T.Q

9(4+x+10)=10(x+10)

126+9x=10x+100

10x-9x=126-100

x=26

Rahul's present age =26years

PROOF

AFTER 10 YEARS HIS AGE=36

RIA'S AGE= 40

RATIO=36:40=9:10
