Question

ratio of two numbers 3:4. if we subtract 5 in each numcer then the ratio become 5:7. find out the numbers​

Answer 1

Answer:

30,40

Step-by-step explanation:

A:B= 3:4

lets take x be the numbers

so 3x : 4x

After subtracting 5

we get: 3x-5/4x-5 = 5/7

After cross multiplication we get:

21x-35= 20x-25

x = 10

so the numbers are A= 10*3 = 30

B = 10*4= 40
