Question

11. The LCM of two numbers is 9 times their HCF. The sum of LCM and HCF
is 500. Find their HCF
duct is 12960 Find their HCF​

Answer 1

Answer:

let x be hcf and 9x be lcm so sum of lcm and hcf =500

9x+x=500

10x=500

x=50

lcm=450

hcf=50

Take lcm as X and Hcf as y. Them according to question x=9y . Them by using other equation which state that Sum of x and y is 500 substitute the value and find y.
