Madhu is thirteenth from the end in a column of girls. There were thrice as many in front of her as there were behind. How many girls are there between Madhu and the fifth girl from the front of the column?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 31
Find Madhu’s place from the front; the girls between two places are the gap between the place numbers, less one.
Madhu is 13th from the end, so 12 girls are behind her
Three times as many are in front of her:
\(3\times12=36\) girls
So Madhu is 37th from the front (and the column has \(36+1+12=49\) girls)
Girls between the 5th and the 37th from the front \(=37-5-1=31\)
