Step-by-step explanation:
Given,
LCM of two numbers is = 120
Ratio of two numbers = 4 : 5
Formula:
Product of two numbers = HCF × LCM
Calculation:
Ratio of two numbers = 4x : 5x
Let the first number be 4x and the second number be 5x, then
HCF of 4x and 5x = x
4x × 5x = x × 120
⇒ x = 120/20
⇒ x = 6
∴ Sum of two number = 4x + 5x = 9x = 9 × 6 = 54
