Answer 2

Answer:

Sameer is 20 & Ravi is 12 years old

Step-by-step explanation:

Let S & R be Sameer & Ravi respectively

S - R = 8

R = S-8 ....(1)

1/S + 1/R = 2/15

(R+S)*15 = 2RS

(S-8+S)*15 = 2(S-8)S

(S-4)*15 = (S-8)S

15S - 60 = S² - 8S

S² - 23 S + 60 = 0

S² - 20S - 3S + 60 = 0

S(S-20) - 3(S-20) = 0

(S-20)(S-3)= 0

S = 20 or S = 3

So, R = S-8 = 20-8 = 12 ...(S can't be 3)
