The LCM of two numbers is 4 times their HCF. The sum of LCM and HCF is 125. If one of the number is 100, then the other number is
-
- 5
- 25
- 100
- 125
Correct Option: B
Let LCM be L and HCF be H, then
According to question ,
L = 4H
sum of LCM and HCF = 125
⇒ H + 4H = 125
⇒ 5H = 125
| ⇒ H = | = 25 | |
| 5 |
∴ L = 4 × 25 = 100
| ∴ Second number = | ||
| First number |
| Second number = | = 25 | |
| 100 |
