The L.C.M. of the two numbers is 35750 and their H.C.F. is 25. If, one of the numbers is 275, what is the other number?
Solution: There are two ways to solve this problem, one create two equations for L.C.M and H.C.F, and solve them to find the second number but a much simple solution would be to use an equation like:
LCM * HCF = Product of the two numbers
Let the second number be Y
Plugging in values, we get,
37550 * 25 = 275 * Y
Y = 3250
Correct Answer: D
