If to a certain number, 720 be added, and the sum be divided by 125 ; the quotient will be equal to 7392 divided by 462. What is that number?
Answers
A) 1280 B) 1270 C) 1260 D) 1250 E) None
Solution   Let x = the number required.   a = 720 d = 7392   b = 125 h = 462   Then by the conditions of the problem (x + a)/b = d/h   Therefore x = (bd - ah)/h   Restoring the numbers,x = [(125.7392) - (720.462)]/462 = 1280.   1280nswer 1280
