. Some boys are sitting in a row. X is sitting 7th from right and Y is sitting 8th from. If there are 4 boys between X and Y. How many boys are there in the row? (a) 9 (c) 10 (b) 8 (d) 7
We know that there are 4 boys between X and Y. So, the arrangement would look like this:
- X is sitting here: _ _ _ _ _ _ X
- Y is sitting here: Y _ _ _ _ _ X
Now, let's count the total number of boys in the row:
- 6 boys to the left of X (including X).
- 5 boys to the right of Y (including Y).
So, the total number of boys in the row is 6 (left of X) + 5 (right of Y) + 1 (X) + 1 (Y) = 13.
So, there are 13 boys in the row. None of the given answer choices (a, b, c, d) matches this count. Please double-check the information provided in the question, as there might be a discrepancy.
