Step-by-step explanation:
For 120 men the provision would last for 30days.
∴ The provision for 1 men would sustain for. 120 x 30 = 3600 days.
Let after the joining of 5 men (after 5 days) the no of more days the provision would last is x days
Now according to the question
⇒ 120 × 30 = 120 × 5 + 125 × x
⇒ 3600 – 600 = 125x
⇒ 3000 = 125x
So, the provision would remain for more 24 days.
