The sum of three numbers is 1331. If the numbers are in the ratio 2:3:6, calculate the difference between the largest and smallest numbers.
Show answer & explanation
Correct answer: D
Explanation
Given:
Ratio of the numbers = 2 : 3 : 6
Total sum = 1331
According to the formula:
Sum = (2 + 3 + 6) × x
2 + 3 + 6 = 11
11x = 1331
x = 1331 / 11 = 121
2x = 242
3x = 363
6x = 726
Difference = 726 − 242 = 484
