Question

Divide 1800 in two parts in such a way that one part is 80% of other part. what is the first part?

Answer 1

let the first part be x

second part will be 80/100 of x

x + 4x/5 = 1800

9x = 9000

x = 1000

so another part will be 800

Answer 2

Answer:

Let the first part be x

And second part =80/100×x

x+4x/5=1800

5x+4x/5=1800

9x=1800×5

9x=9000

x=1000

First part =1000

And second part = 4/5×1000

= 4×200

=800.
