Question

two numbers are 10% and 20% of third number find ratio of two numbers​

Answer 1

Answer:

let the third number be x

then,

1st number=10% of x

                 =$\frac{10}{100}$ × x

                 =$\frac{x}{10}$

2nd number=20% of x

                    =20/100 × x

                    =x/5

ratio=1st number: 2nd number

       =x/10 : x/5

       =1/2 : 1

       =1:2
