The sum of two numbers is 2490. If 6.5 % of one number is equal to 8.5 % of the other then the numbers are:_________?
Correct Answer: D. 1411, 1079 Explanation: Let the number be x and (2490 – x). Then 6.5 % of x = 8.5 % of (2490 – x) => 6.5/100 × x = 8.5/100 × (2490 – x) => 65x/1000 = 85(2490 – x)/1000 => 65x = (85 × 2490) – 85x => 150x =(85 × 2490) => x = 211650/150 = 1411 Hence the numbers are 1411 and (2490 – 1411) = 1079
