Four numbers are in the ratio of 1 : 3 : 5 : 4. Sum of these numbers is 52. What is the difference between the largest and smallest number?
Show answer & explanation
Correct answer: B
Explanation
Ratio of the numbers = 1 : 3 : 5 : 4
Let the numbers be x, 3x, 5x, and 4x
Sum = 52
13x = 52
x = 4
The numbers are 4, 12, 20, 16
Difference between the largest and smallest numbers = 20 - 4 = 16
