If numbers are in a ratio 2 : 5 : 3 : 4, and the numbers are increased by 20%, 30%, 40% and 10% respectively. Find the new ratio.
Show answer & explanation
Correct answer: D
Explanation
Ratio of numbers = 2 : 5 : 3 : 4
Increase = 20%, 30%, 40%, 10%
New numbers = 2 × 1.20 : 5 × 1.30 : 3 × 1.40 : 4 × 1.10
= 2.4 : 6.5 : 4.2 : 4.4
= 24 : 65 : 42 : 44
