Question

two numbers are in the ratio 3 is to 4. When 3 is added to the ratio it changes to 4:5 what is the sum of the two numbers

Answer 1

x/y=3/4

(x+3)/(y+3) = 4/5

x=9, y=12 sum of the two numbers is 9+12 = 21

9/12 = 3/4

12/15 = 4/5

It comes out even this way.

that's the only way I see to interpret the problem.

just adding 3 to 3/4 won't = 4/5
