Question

Three numbers A, B and C are in the ratio 4 ∶ 5 ∶ 8, If each number is increased by 15%, 24% and 35%, respectively, then the new ratio of the numbers will be:

• A. 23 ∶ 31 ∶ 54
• B. 21 ∶ 31 ∶ 54
• C. 23 ∶ 31 ∶ 44
• D. 23 ∶ 33 ∶ 54

Answer 1

Answer:

A. 23 ∶ 31 ∶ 54

Let the numbers be 4p, 5p, and 8p respectively. 4p + 4p × 15% : 5p + 5p × 24% : 8p + 8p × 35% = 4p + 0.6p : 5p + 1.2p : 8p + 2.8p = 4.6p : 6.2p : 10.8p = 46 : 62 : 108 = 23 : 31 : 54
