In a row of children, Ravi is fourth from right and Sham is second from left. When they interchange positions Ravi is ninth from right. What will be Sham's position from left?
Correct Answer: Seventh
Explanation:
According to question ,
Here, S = sham , R = Ravi
Children between S and R = position of S - position of R
Children between S and R = 9 – 4 = 5 children
Hence new position of S = 2nd position + 5 children = 7th.
