Answer 1

Find the amount of provision left after 5 days:

120 men has provision for 30 days

At the end of 5 days:

120 men has provision for 25 days

.

Find the amount of days the remaining provisions can provide:

Number of men = 120 + 5 = 125

.

120 men has provision for 25 days

1 man = 25 x 120 = 3000 days

125 men = 3000 ÷ 125 = 24 days

.

Answer: The remaining provision can provide for 24 days.
