Question

Ratio of two numbers 2:3 if 9 will be added inevery number then what is the ratio of 3:4

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
