Question

11 If two numbers are respectively, 25% and 40% less than the third number, what is the ratio of these two numbers?
​

Answer 1

Answer:

5:4

Step-by-step explanation:

let the third number x

than first no. will be :- x × 25/100 = x/4

so the first no. is 25% less than third no

therefore, x - x/4 = 3x/4

first number => 3x/4

second no. :- x × 40/100 = 2x/5

x - 2x/5 = 3x/5

second number => 3x/5

ratio of first number and second number =

3x/4 ÷ 3x/5 = 5/4

= 5/4
