Explanation

He sold 20 articles for Rs. 60 and gained 20%.

Let C.P. of 1 article = x

Then, S.P. of 1 article = x × 1.2

So for 20 articles:

20 × 1.2x = 60

→ x = 60/24 = 2.5

Thus, cost of 1 article = Rs. 2.5

Now, how many articles can he buy for Rs. 60?

60 ÷ 2.5 = 24

Explanation

Given:

Food for 24 men = 29 days

So, total food = 24 × 29 = 696 man-days (means food for 696 men for 1 day).

They eat for 4 days first:

In 4 days, 24 men eat = 24 × 4 = 96 man-days of food.

Remaining food = 696 − 96 = 600 man-days.

Now, 1/6 of 24 men leave → 24 × (1/6) = 4 men leave.

Remaining men = 24 − 4 = 20 men.

Now 600 man-days of food for 20 men → 600 ÷ 20 = 30 days.
