Question

The present ages of Riya and Priya are in the ratio 5: 4. After 8 years the ratio of their ages will be 6: 5. The present age of Priya is ......

Answer 1

Answer:

present ages of riya and priya is 5x, 4x

after 8 years 5x+8, 4x+8=6:5

5x+8=6y

4x+8=5y

multiplying 1equation by 4 and second by 5 and then subtracting

20x+32=24y

20x+40=25y

now subtracting

y=8

so x will be 5x+8=48

x=8

so present age of riya will be 5×8=40
