Question

a bag contains red and white balls. the ratio of red to white balls is 3:4. if the bad contains 36 white balls then find the number of red balls?

Answer 1

48

Explanation:

If the ratio is 3:4, we can just divide 35 by 3.

Then we get 12, and to get the red balls we can multiply by 4 because that is the ratio

4*12= 48

there are 48 red balls

Answer 2

P (of red ball) = 1 - ( 310 + 25 ) = 1 - (3 + 410 ) = 1 - 710 = 10 - 710 P (of red ball) = 310 No. of black balls = 20total no. of balls 25 = 20total balls
