Question
1250 oranges were distributed among a group of girls of a class. Each girl got twice as many oranges as the number of girls in that group. The number of girls in the group was = ?
Answer: Option A
Let the number of girls in the group be x
Then, number of oranges given to each girl = 2x
$$\eqalign{
& \therefore x \times 2x = 1250 \cr
& \Leftrightarrow 2{x^2} = 1250 \cr
& \Leftrightarrow {x^2} = 625 \cr
& \Leftrightarrow x = 25 \cr} $$
