Answer 1

Answer:

Two numbers are 65 and 78

Step-by-step explanation:

let the two numbers be x and 143-x

Therefore, 20% of x + x = 143-x

20/100 of x + x = 143 - x

x/5 + x = 143- x

6x/5=143-x

6x/5+x=143

11x/5 = 143

x = 143 multiply 5/11

x=13 multiply 3

=65

second no.=143-x=78

Answer 2

in the same way apply for 78...
