Two numbers are in the ratio 7 : 11. If their HCF is 28, then the sum of the two numbers is:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e 504.
Given:
Ratio of numbers = 7 : 11
HCF = 28
Calculation:
Let the numbers be 7x and 11x
HCF of 7x and 11x is x
⇒ HCF = x = 28
The numbers will be 7 × 28 and 11 × 28
The numbers will be 196 and 308
Sum of numbers = 196 + 308 = 504
