Question

The HCF of two numbers is 5 and their LCM is 200. If one of the number is 25, the other is:
1. 40
2. 27
3. 35
4. 30

Answer 1

Correct Answer - Option 1 : 40

Given:

The HCF of two numbers = 5 

The LCM of their number = 200 

One of the number = 25

Formula used: 

HCF × LCM = First number × second number 

Calculation:
⇒ 5 × 200 = 25 × second number 

⇒ 1000 = 25 × second number 

⇒ second number = 1000/25 = 40 

∴ The other number is  40.
