A store has provision which would last for a certain number of men for...
To solve this problem, we can use the concept of proportions. Let's assume that the store has provisions for x men for 21 days.
We are asked to find how many days the provisions will last for one-seventh of the men. One-seventh of the men can be represented as (1/7) * x.
To find the number of days the provisions will last for one-seventh of the men, we need to set up a proportion:
x men / 21 days = (1/7) * x men / y days
where y is the number of days the provisions will last for one-seventh of the men.
To solve for y, we can cross multiply:
x * y = (1/7) * x * 21
Simplifying the equation:
y = (1/7) * 21
y = 3
Therefore, the provisions will last for 3 days for one-seventh of the men.
Hence, the correct answer is option A) 147.
