Question

I WANT SOLUTION AND EXPLANATION ANSWER IS GIVEN AT LAST!!!

Answer 1

let the numbers be x and y

x + y = 1600 ----*

12%x = 20%y

0.12x = 0.2y

y = 0.12x

0.2

y = 0.6x

substitute in * eqn

x + 0.6x = 1600

1.6x = 1600

x = 1000

then,

y = 0.6*1000

y = 600

the numbers are 1000 and 600
