QUESTION: 1

In a queue, Amrita is 10th from the front while Mukul is 25th from behind, and Mamta is just in the middle of the two. If there are 50 persons in the queue, what position does Mamta occupy from the front?

Solution: According to the question,

Amrita is 10th from the front, which means there are 9 people ahead of Amrita.

Mukul is 25th from behind, which means that there are 24 people behind him.

If Mamta is exactly between Amrita and Mukul, then there are an equal number of people between Amrita, Mamta, and Mamta, Mukul.

The question states that there are a total of 50 people in the queue; this simply means that there are 7 people between Amrita, Mamta, and Mamta, Mukul.

From this, we can easily derive that Mamta is 18th from the front.

Hence, the correct option is (C).

QUESTION: 2
