Number SystemModerateSSC CGL 2023
The HCF and LCM of two numbers are 5 and 140 respectively. If one of the numbers is 20, what is the other number?
- (A)40
- (B)30
- (C)7
- (D)35
Correct answer: (D) 35
For any two numbers, product of the numbers = HCF × LCM. So the other number = (5 × 140) ÷ 20 = 700 ÷ 20 = 35.
Shortcut: Other number = HCF × LCM ÷ given number.
