In a row of children, P is 17th from the left and Q is 15th from the right. If R is 6th to the right of P and is exactly in the middle of P and Q, what is the total number of children in the row?
Show answer & explanation
Correct answer: D
Explanation
Correct Answer: Option 4 (43)
Logic & Explanation:
-
Position of P: 17th from the left.
-
Position of R: Since R is 6th to the right of P, there are exactly 5 children between P and R.
-
Position of Q: R is exactly in the middle of P and Q. Because there are 5 children between P and R, there must also be exactly 5 children between R and Q.
Total Calculation:
-
Children to the left of P = 16
-
P itself = 1
-
Children between P and R = 5
-
R itself = 1
-
Children between R and Q = 5
-
Q and children to its right = 15 (since Q is 15th from the right)
Total = 16 + 1 + 5 + 1 + 5 + 15 = 43
