Question

There are 900 beads in a box. 45% of them are black, 60% of the remainders are white and the last remaining are red. How many red beads are there in the box?

Answer 1

Answer:

198

Step-by-step explanation:

Given that there is a total of 900 beads in the box.

Find the number of black beads

Number of black beads = 45% x 900 = 0.45 x 900 = 405

Find the remaining beads

Remaining beads = 900 - 405 = 495

Find the number of white beads

Number of white beads = 60% x 495 = 0.6 x 495 = 297

Find the number of red beads

Number of red beads = 900 - 405 - 297 = 198

Answer: 198 red beads
