A stock of food is enough for 315 men for 48 days. For how many days the same stock of food is enough, if 45 more men join?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 42.
We know that,
(M1 × D1 × H1)/W1 = (M2 × D2 × H2)/W2
where,
M = men, D = days, and H = Hours
Let the number of days be D
315 × 48 = (315 + 45) × D
315 × 48 = 360 × D
D = (315 × 48)/360
D = 42 days
