A can do a piece of work in 1/25 days .
B can do a piece of work in 1/30 days.
They together work in 1/25 + 1/30 days
25/30 = 30 + 25 / 750 = 55/750th work in the day.
In 5 days A & B together complete 5 × 55/750
= 275/750 = 11/30 of the work.
So, the work left is 1 - 11/30 = 30 - 11 / 30 = 19/30.
i hope it will help u ❤️
