Correct Answer - Option 3 : C

Given:

The number of women on the train is half the number of men. In Faridabad city, 10 men get off the train and five women enter the train.

Concept Used:

Concept of the linear equation of one variable

Calculation:

Let, the number of men in the train is 2x

Accordingly, the number of women on the train is x

In Faridabad city, 10 men get off the train and five women enter the train.

Now, the number of men in the train is (2x - 10) and the number of women in the train is (x + 5)

Accordingly,

(2x - 10) = (x + 5)

⇒ 2x - x = 5 + 10

⇒ x = 15

In the beginning, the number of women on the train was 15 and the number of men on the train was 15 × 2 = 30

At the beginning number of passengers in the train was (30 + 15) = 45

∴ In the beginning, 45 passengers entered the train.
