In a row of boys, Deepak is 9th from the left and Kavya is 12th from the right. If they exchange their positions, Deepak becomes 18th from the left. What will be the position of Kavya from the right?
Show answer & explanation
Correct answer: B
Explanation
Kavita's position from the left = 18
Total number of boys
Formula: Total = Left position + Right position - 1
Total = 18 + 12 - 1 = 29
Now Kavita's new position (from the right)
Kavita will now move to Deepak's old position (9 from the left).
Right position = 29 - 9 + 1
= 21
