Question

in a necklace after every 5 yellow beads there are two red beads. If the total number of beads in the necklace are 497, find the number of red and yellow beads.​

Answer 1

Step-by-step explanation:

yellow beads =5x

red beads =2x

total beads =497

so, 5x +2x =497

7x =497

x=497 / 7

x=71

therefore , yellow beads = 5*x=5*71=355

red beads. =2*x =2*71=142
