Question

3. Two numbers are respectively 20% and 40% more than a third number. What
is the ratio of two numbers?
​

Answer 1

Step-by-step explanation:

let the number be x

then 1st number is x+20x/100 that amplies x+x/5=6x/5

and 2nd number is x+40x/100 that amplies x+2x/5=7x/5

ratio =x:6x/5:7x/5

x will be cancelled off as it is common

by multiplying each and every term by 5 to make them integers we'll get

5:6:7
