Question

The sum of two numbers is 1600. If 12% of one is equal to 20% of the other, then find the numbers

Answer 1

Answer:

Step-by-step explanation:

x+y=1600

12x/100=20y/100

3x=5y

x=5y/3

5y/3+y=1600

8y/3=1600

y=600

x=1000

Answer 2

Answer:

x + y = 1600, so x=1600-y

12/100*x = 20/100*y

12/100(1600 - y) = 20/100*y

12*16 - 3/25*y = 1/5*y

192 = 1/5*y + 3/25*y

192 = 8/25*y

192*25 = 8y

Therefore, y=600

12/100*x = 20/100*600

Therefore, x=1000

Therefore, x=1000, y=600

Hope this helps.
