In a row of 40 girls, when Komal was shifted to her left by 4 places her number from the left end of the row became 10. What was the number of Swati from the right end of the row if Swati was three places to the right of Komal's original positions?

A) 22                               

B) 23

C) 25                               

D) 24

Correct Answer: D

Solution :

On shifting 4 the left Komal is 10th from the left end of the row. Thus, Komal's original position was 14th from the left end. Swati is 3 places to the right of Komal's original positions Clearly, swati is 17 th from the left end. Number of girls to the right of swati \[=(40-17)=23.\] Thus, Swati is 24th from the right end of the row.
