The LCM of two numbers is 168 and their HCF is 12. If the difference between the numbers is 60, what is the sum of the numbers? |
112 116 108 122 |
108 |
⇒ (Product of two other factors) × HCF = LCM ⇒ (a × b) × 12 = 168 ⇒ (a × b) = 14 So a and b = 7 and 2 Therefore, numbers are: = (a × HCF), (b × HCF) = (7 × 12), (2 × 12) = 84 , 24 ATQ, Difference = 84 - 24 = 60 (given) So, Sum of two numbers = 84 + 24 = 108 |
