Question

Ratio of the number of red beads and blackheads in a box is 6 : 5. If the number of red beads is 4 more than the number of black beads find the number of red beads and black beads in the box.

Answer 1

Let the number of red beads = 6x

Number of black beads = 5x

6x – 5x = 1x ; = 6x – 5x = 4

This is given as 4. 

∴ x = 4

Number of red beads = 6 × 4 = 24

Number of black beads = 5 × 4 = 20
