Let ,
Ravi draw n fruits
As the probability of drawing an apple from the bag is 6/25 , the probability of each fruit drawn by ravi being an apple is also 6/25.
As he drew n fruits , the average number pf apples would be 6/25 * n
we want it to be 12.
So , equating (6/25)*n to 12
ie (6/25)*n = 12
n = 50.
