hello friends,
my question is
The L.C.M of two numbers is 495 and their H.C.F is 5. If the sum of the numbers is 10, then their difference is,.............
please explain me ....
thanks
\(\displaystyle |ab| = 495\cdot 5\)
\(\displaystyle a+b = 10\)
So?
so..........
the required difference is 55-45 =10 ................Incorrect
thanks ...........
so..........
the required difference is 55-45 =10
thanks ...........
How did you get that? Please show work.
hi
below is the work i did ...
let the numbers be x and (10-x) then,
x(10-x)=5*495
x2-10x-2475=0
(x-55)(x+45)=0
x= +55 or x=-45
the numbers are 55 and 45....... Numbers are 55 and -45
required difference= 55 - (-45) = 100
(55-45)=10
This is incorrect.hi
