Question

The ages of Raju and Ravi are in the ratio 3:4 .Four years from now the ratio of their ages will be 4:5 . Find their present ages.

Answer 1

raju=16 years

Ravi=20 years

Explanation:

raju =4×4=16

Ravi=5×4=20

Answer 2

Age of Raju = 12

Age of Ravi = 16

Explanation:

Let the Ages of Raju and Ravi be 3x and 4x years

According to question,
`(3x+4)/(4x+4)` =
`(4)/(5)`

⇒ 5(3x+4)=4(4x+4)

⇒ 15x+20 = 16x+16

⇒ 15x−16x=16 - 20

⇒ −x = −4

⇒ x = 4

Age of Raju = 3 × 4 = 12

Age of Ravi = 4 × 4 = 16
