Ramesh's luggage bag initially weighed 15 kg when he started his tour. By the time of his departure, the weight of his bag had increased to 18 kg. Calculate the percentage increase in the weight of the luggage.

Correct option is C

Given:

Initial weight of the luggage = 15 kg
Final weight of the luggage = 18 kg

Concept Used:

The percentage increase in the weight of the luggage can be calculated using the formula:
Percentage Increase = $$\frac{(Final Weight - Initial Weight) }{Initial \ Weight} × 100$$​​

Solution:

The increase in the weight of the luggage is:
Increase in weight = 18 - 15 = 3 kg
The percentage increase in weight is:
Percentage Increase = (3 / 15) × 100 = 20%
Thus, the percentage increase in the weight of the luggage is 20%.
