Question 1:
The L.C.M of two numbers is 495 and their H.C.F is 5. If the sum of the numbers is 100,then their difference is
A. 10
Feedback Let the numbers be x and (100-x).
Then,x(100−x)=5*495
=> x2−100x+2475=0
=> (x-55) (x-45) = 0
=> x = 55 or x = 45
The numbers are 45 and 55
Required difference = (55-45) = 10
Then,x(100−x)=5*495
=> x2−100x+2475=0
=> (x-55) (x-45) = 0
=> x = 55 or x = 45
The numbers are 45 and 55
Required difference = (55-45) = 10
B. 46
C. 70
D. 90
