Question

The LCM and HCF of two numbers are 200 and 5 respectively. If the one is 25, what is the other number?

1. 90
2. 40
3. 20
4. 60

Answer 1

Correct Answer - Option 2 : 40

Given:

LCM = 200

HCF = 5

One number = 25

Concept:

HCF × LCM = First number × Second number

Calculation:

 Let, the other number = x

According to the question,

⇒ 5 × 200 = 25 × x

⇒ (5 × 200)/25 = x

⇒ 40 = x

∴ Required number = 40
