Question

The lcm of two numbers is 35 times their hcf. If one number is 90 and sum of their hcf and lcm is 1080. Find the other number.

Answer 1

lcm=x
hcf=35x

lcm+hcf=1080
x+35x=1080
36x=1080
x=1080/36
x=30

lcm= 30
hcf=30×35=1050

no.1 × no.2= lcm×hcf
90 × no.2= 30×1050
no.2= 31500/90
no.2= 350

Answer 2

Answer:

LCM of two numbers is 35 times their HCF . If one of the numbers is 90 and sum of their
