Question

The two numbers are in the ratio of 2:9. if 10 be added to each, they are in the ratio of 3:10.find the numbers

Answer 1

Answer:

Let their common ratio is x

then numbers will be 2x and 3x

when 9 is added to each they become (2x+9)and (3x+9)

so their ratio

(2x+9)/(3x+9)=3/4

8x+36=9x++27

x=36–27

x=9 so the original numbers will be

2x=2*9=18 and 3x=3*9=27

so their product will be

18*27=486
