In a row of 21 girls, when Monika was shifted by four places towards the right, she became 12^th from the left end. What was her earlier position from the right end of the row ?

1. 9th
2. 10th
3. 11th
4. 14th

Answer 1

Correct Answer - Option 4 : 14th

In a row of 21 girls, when Monika was shifted by four places towards the right, she became 12th from the left end.

Let us assume that earlier Monika was at 'x'th position from the left end.

After being shifted by four places towards the right, her new position becomes (x + 4)th, which is equal to 12th from the left end.

Therefore, we can write:

x + 4 = 12

⇒ x = 12 - 4

⇒ x = 8

So, Monika's position from the left end of the row is 8th.

Therefore, her position from the right end of the row = (21 - 8) + 1

= 13 + 1

= 14

Hence, ‘14th’ is the correct answer.
