Question

two numbers are in the ratio 5:7. if the sum of the number is 72. Find the other number​

Answer 1

Answer:

let the two numbers be x and y

ratio = 5:7

x/y = 5/7

x = 5y/7

sum of numbers = 72

x + y = 72

5y/7 +y = 72

5y + 7y = 72

7

12y = 72×7

y = 72×7/12

y = 42

x = 5y/7 = 5×42/7 = 30

x = 30

the numbers are 30 and 42

Answer 2

Answer:

5x+7x=72

12x=72

x=72/12

x=6

numbers:-

5x=5*6=30

7x=7*6=42
