Question

(1) Angad takes 15 days more than Aarav to complete a work, if they work alone. If they work together, they complete the work in 4 days. Find how much time each takes to complete the work alone.​

Answer 1

Answer:

Angad takes 20 days while Aarav takes 5 days.

Step-by-step explanation:

let Angad takes x + 15 days

1 day work of Angad = 1/ (x + 15)

and Aarav takes x days

1 day work of Aarav = 1 / x

Aarav + Angad takes 4 days

so 1 day work of them together = 1/ 4

from above

1/ x + 1 / (x + 15) = 1/ 4

on solving

x = 5

so Aarav takes 5 days

and Angad takes 20 days.
