The ratio of two numbers is 3:4 and their HCF is 15.
Then the sum of the two numbers is:
(a) 70
(b) 120
(c)105
(d) 125
If the more of the sum of two numbers is equal to 4​

Answer 1

Answer:

105

the ratio of the number is 3:4

the HCF is 15

so the numbers are 15×3=45, 15×4=60

so the sum of two numbers are (45+60)=105

Answer 2

The sum of two numbers is 105

Solution:

Given that,

Ratio of two numbers is 3 : 4

Let the first number be 3x

Let the second number be 4x

Given that,

HCF = 15

Therefore,

x = 15

First number = 3x = 3(15) = 45

Second number = 4x = 4(15) = 60

Thus sum of two numbers = 45 + 60 = 105

Thus sum of two numbers is 105
