Multiple choice general knowledge math & puzzles

Two numbers are respectively 20% and 50% more than a third number. The ratio of the two numbers is:

  1. 2:5

  2. 3:5

  3. 4:5

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Let the third number be x. First number = 1.2x = 6x/5, second number = 1.5x = 3x/2. Ratio = (6x/5):(3x/2) = 12:15 = 4:5. Option C is correct.

AI explanation

Let the third number be N. The first number is 120% of N = 1.2N, and the second is 150% of N = 1.5N. The ratio of the two is 1.2N : 1.5N = 12:15 = 4:5 (dividing both by 3). This simplification directly gives the answer regardless of N's actual value, since N cancels out. The other ratios (2:5, 3:5) don't match this simplified fraction.
