Answer :
a/b = 20
a + b = 84
b = 84 - a
a / (84 - a) = 20
a = 20 (84 - a)
a = 1680 - 20a
21a = 1680
a = 1680/21
a = 80
b = 84 - a
b = 84 - 80
b = 4
Therefore, the two numbers are 80 and 4
a + b = 84
b = 84 - a
a / (84 - a) = 20
a = 20 (84 - a)
a = 1680 - 20a
21a = 1680
a = 1680/21
a = 80
b = 84 - a
b = 84 - 80
b = 4
Therefore, the two numbers are 80 and 4
