In a row of 40 girls, when Kavita was shifted to her left by 4 places her number from the left end of the row becomes 12. What was the number of Suman from the right end of the row if Suman was three places to the right of Kavita's original position?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 22
All positions are first found from the left end; the last one is then turned into a position from the right, where a girl at position \(p\) from the left is \(40-p+1\) from the right.
After moving 4 places to her left Kavita is 12th, so she was originally \(12+4=16\)th from the left
Suman is 3 places to the right of that, so she is \(16+3=19\)th from the left
From the right end: \(40-19+1=\) 22nd
