Question

two numbers are in the ratio 3:4 when 5 added to each number, their ratio becomes, 7:9 , find the numbers​

Answer 1

Answer:

30 and 40

Step-by-step explanation:

3x+5/4x+5=7/9

=> 3x+5=7/9(4x+5)

= 3x+5= 28x/9+35/9

=>3x-28x/9=35/9-5

-x/9=-10/9.

-x=-10/9*9

-x=-10

=>x=10

the original no.s were 3x and 4x respectively.we found x=10.

now the first no. 3x=3*10=30

the other no.=4*10=40
