The LCM of two numbers is 4 times their HCF. The sum of LCM and HCF is 125. If one of the numbers is 100, then the other number is
Let one of the numbers = $$x$$ and other number = 100
Let L.C.M = $$L$$ and H.C.F = $$H$$
According to ques, => $$L=4H$$ --------------(i)
and $$L+H=125$$
Substituting value from equation (i), we get : $$4H+H=5H=125$$
=> $$H=\frac{125}{5}=25$$
=> $$L=4\times25=100$$
Thus, product of numbers = $$L\times H$$
=> $$100\times x=100\times25$$
=> $$x=25$$
