PLEASE MARK ME AS BRAINLEST.

Answer 2

answer is- 12 days

Step-by-step explanation:

Vijay can do 1/30 of the total work in one day

while

ajay can do 1/20 of the total work per day

so

(1/30 added to 1/20) x times = 1

=> 5

$\frac{5}{60} x$

5/60 x = 1

where x is number of days

so x is equal to 12 days
