Question

A basket contains red,blue and yellow coloured balls. 50% of the total no of ballls are red, 20% of the remaining balls are blue, how many balls are yellow in colour given that the total no of balls in the basket is 250

Answer 1

Answer:

100 yellow balls

Step-by-step explanation:

Total number of balls are 250.

50% of 250 is 125 red.

Remaining balls, 250–125=125

20% of 125= 0.2*125=25 blue

Since there are only red, blue and yellow balls, everything apart from red and blue balls is yellow.

=> 250–125–25=100 yellow balls
