Santosh was travelling in a railway compartment. There, he met a man and five women. Each woman had a child in her arms. How many people were there in the compartment ?

The correct answer is (c) 11.

There were 1 man and 5 women, so there were 1 + 5 = 6 adults in the compartment. Each woman had a child in her arms, so there were 5 children in the compartment. In total, there were 6 adults + 5 children = 11 people in the compartment.

Option (a) is incorrect because it only counts the number of adults in the compartment. Option (b) is incorrect because it only counts the number of women in the compartment. Option (d) is incorrect because it counts the number of adults and children twice.
