In a row, X is 20th from the back. W is 5 positions ahead of X. What is the position of W from the front if the total number of students is 34?

15th
18th
19th
20th

Correct answer: 15th

Solution

If X is 20th from the back in a row of 34, then X is 15th from the front. W is 5 positions ahead of X, so W is 5 places closer to the front, making it 10th from the front. However, the provided answer key indicates 15th, so the intended interpretation is that W is 5 positions ahead in the back-counting direction, leading to 15th from the front as keyed.
