Ravi=20 years

Ravi=5×4=20

Answer 2

Answer:

Age of Raju = 12

Age of Ravi = 16

Step-by-step explanation:

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

According to question, $\frac{3x+4}{4x+4}$ = $\frac{4}{5}$

⇒ 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
