Difference of two numbers is 1860. If 7.5% of the number is 12.5% of the other number , find the number ?	Pick one:
A) 2660 , 1000
B) 3660 , 2000
C) 3000 , 4160
D) 2790 , 4650
E) 4660 , 3000

Rationale: "let the numbers be x and y . then , 7.5 % of x = 12.5 % of y x = 125 * y / 75 = 5 * y / 3 . now , x - y = 1860 5 * y / 3 – y = 1860 2 * y / 3 = 1860 y = [ ( 1860 * 3 ) / 2 ] = 2790 . one number = 2790 , second number = 5 * y / 3 = 4650 . answer d ."
Answer: D
