Answer:

mark as brainliest

Step-by-step explanation:

Answer:

let 1st no is x so 2nd will be 1600-x

a.t.q.

12% of 1st=20% of 2nd

0.12x= 0.20(1600-x)

0.12x= 320-0.20x

0.32x= 320

x= 320 / 0.32

x= (320 * 100) / 32

x=1000 --Ans

Answer 2

Let the first number be x and the second number be y.

Given : The sum of two numbers is 1600.

i.e.    (1)

12% of one number = 0.012x

20% of the other number = 0.20y

If 12% of one is equal to 20% of the other

Put y=0.6x in (1) , we get

From (1) , y= 600

Hence, the numbers are 1000 and 600.Answer:

The numbers are 1000 and 600.
