Question

The LCM of two numbers is 20 times of their
HCF and (LCM + HCF) = 2520. If one number is
480, what will be the triple of another number?​

Answer 1

LCM = 20 × HCF (given)

Let HCF = x

LCM = 20x ( according to given condition)

LCM + HCF = 2520

20x + x = 2520

21x = 2520

x = 2520 / 21

x = 120

The HCF is 120

The LCM is 2400

One number is 480

Other nunber is y

The product if the two number is = HCF × LCM

480 × y = 120 × 2400

y = 120 × 2400/480

y = 600

The other number is 600.
