Answer:
y = 297
Step-by-step explanation:
We know,
[tex]\boxed{\sf LCM * HCF = Product \: of \: 2 \: numbers \: involved \: in \: HCF \: and \: LCM}[/tex]
Given, two numbers = x and y
LCM of them: 2079
HCF of them: 27
So, putting the values:
Also given,
Multiply both sides by 9:
Putting the value of x in eqn (1):
Divide both sides by 21*9:
