Given:
Number of girls = 20
Total number of oranges plucked by all girls = 200
To find:
How many oranges can be plucked by one of them?
Solution:
We can use the formula:
Total number of oranges / Number of girls = Number of oranges plucked by one of them
Substituting the given values in the formula, we get:
200 / 20 = 10
Therefore, each girl can pluck 10 oranges.
Answer:
Option A) 24 is incorrect.
Option B) 10 is correct.

Suppose all of them plucked the different number of oranges. A girl can pluck at least 0 oranges and the number of oranges plucks by each student is distinct. So, total number of plucked oranges should be less than 100. But 0+1+2…..+19+20 = 210>200 a contradiction.
Thus there exist two girls who plucked the same number of oranges. If thus there exist two girls who plucked the same number of oranges. It means each girl of remaining 18 students plucked different number of oranges. Number of oranges Plucked by 18 students = 0+1+2+3…+17 = 153 oranges. Number of oranges plucked by remaining 2 student = 200 – 153 = 47. Both students plucked same number of oranges. So, Number of oranges plucked by one of them = 47/2=24.
