Answer: A) For a pair of pom pom,
Total white strands = 56
Total blue strands = 40
Total red strands = 64
B) Required proportions,
White strands: w/80 =35/ 100
Blue strands: b/80=25/100
Red strands: r/80=40/100
Step-by-step explanation:
Since, According to the question,
Total number of strands for each pom-pom = 80
Also, A pom-pom manufacturer makes each of its pom-poms with 35% white strands (w), 25% blue strands (b), and 40% red strands (r).
Thus, In each pom-pom,
White strands = 35% of 80 =
Blue strands = 25% of 80 =
Red strands = 40% of 80 =
A) Thus In pair of pom-pom,
White strands = 2×White strands in each strands = 2 × 28 = 56
Blue strands = 2× Blue strands = 2 × 20 = 40
Red strands = 2 × 32 = 64
B) Since, Here w represents white strands, b represents blue strands and r represents red strands,
Thus, w = 35% of 80
⇒
⇒ (On dividing both sides by 80)
Similarly,
And,
Which are the required proportions.
