Correct Answer - Option 3 : C
Given:
Ratio of three numbers = 2 : 3 : 6
HCF = 45
Calculation:
let the number be 2x, 3x, 6x
HCF is the common factor for all numbers
adding all the number = 2x + 3x + 6x = 11x
∵ both the x and HCF is common in all the number
Substituting the value of HCF in x
Sum of the three numbesr = 11 × 45 = 495
∴ The sum of the three number is 495
