Question

A bag contains white, blue and red ping-pong balls in the ratio 8 : 3 : 2. There are 10 balls. If 10 white and 10 blue balls are removed from the bag, the new ratio is ?

Answer 1

Assume that there are 10 red balls.

Before removing the balls from the bag

Number of red balls=10=2×X ;then X=5

Number of white balls=8×5=40.

Number of blue balls=3×5=15.

After removing balls from bag

Number of white balls=40-10=30.

Number of blue balls=15-10=5.

The new ratio is white:blue:red=

30:5:10=6:1:2
