Question

Two numbers are 20% and 50% more than a third number, what percent is the first of the second ? Select one: a. 80% b. 40% c. 70% d. 60%

Answer 1

If the third number is 100, then first number = 100 x (20 / 100) = 20. and second number = 100 x (50 / 100) = 50. when third number is 100, then first number is 20 . when third number is 1, then first number is 20/ 100 . when third number is 100, then first number is (20 / 100) x 100 = 20% ∴required percentage = 20%.
