Question

the difference between 2 numbers is 48 the ratio of the 2 number is 7:3

Answer 1

Step-by-step explanation:

difference between tel number is 48, therefore, x-y=48 ...... (1)

x=48+y

the ratio of the 2 number is 7:3 therefore, x/y=7/3

3x=7y

x=7y/3

now, put the value of x in equ (1)

7y/3-y=48

7y-3y/3=48

4y/3=48

4y=14

now, y=144/4

hence, y=36

and, x=48+y

=48+36

x=84

so, x =84 and y =36 is right answer
