In a row of 25 students facing north, Manoj is 15 th from the right end. If Harish is 10 th to the left of Manoj, what is Harish's position from the left end of the row?
1 st
2 nd
3 rd
4 th
1 st
In a row, position from the left = Total - (position from right - 1). For shifting left: simply subtract the 'n' places from the current rank from the left.
In a row, position from the left = Total - (position from right - 1). For shifting left: simply subtract the 'n' places from the current rank from the left.
Calculate Manoj's position from left
Total students = 25. Manoj is 15th from the right. Manoj's position from left = (Total - Rank from right) + 1 = (25 - 15) + 1 = 11th.
Determine Harish's position
Harish is 10th to the left of Manoj. Harish's position = Manoj's position from left - 10 = 11 - 10 = 1st from the left.
B: 2nd is incorrect as the calculation 11-10 yields 1. C: 3rd is incorrect. D: 4th is incorrect.
A is correct because calculating Manoj's left-side rank as 11th and shifting 10 places left results in 1st place.
Remember that when calculating rank from the opposite end, always add 1 because the person is counted twice if you simply subtract.
