Question

Two numbers are 30% and 20% less than a third number respectively. The ratio of first two numbers is:​

Answer 1

Answer:

$\huge\bigstar\underbrace{\mathtt\red{A} \mathtt\purple{N} \mathtt\green{S}\mathtt\blue{W} \mathtt\blue{E} \mathtt\orange{R}}\bigstar$

Step-by-step explanation:

Let 3rd no = 100

Then 30% less than 100 will be ((100-30)/100)*100=70

Similarly 20% less will be 80

The ratio is 7:8

[Percent is the first number of the second=(70/80)*100=87.5%]

Answer 2

Answer:

hey here your answer...

hope you understand..

Step-by-step explanation:

Let the third number be 100.

Then, the first number = 100 - 20 = 80 and second number = 100 - 30 = 70.

Difference between the first and second number = 80-70 = 10

Required percentage = 1080 x 100% = 100/8 = 12.5%
