Answer 2

Given :

The sum of two numbers is 1600. If 12 %of one of the number is equal to 20% of the other.

ㅤㅤ

To find :

What are the numbers?

ㅤㅤ

Concept :

1) Let us assume, "x" and "y" as first and second numbers.

ㅤㅤ

2) Here, we use "x" and "y" as a variables instead of using "First number, Second number" in every equation.

ㅤㅤ

3) Using the variables make easier to understand the equation.

ㅤㅤ

4) We learn about variables in the chapter "Linear equations and variables".

ㅤㅤ

5) Remember that, 12℅ in decimal form is equal to 0.12 and 20℅ in decimal form is equal to 0.20.

ㅤㅤ

Calculations :

→ x + y = 1600

→ 0.12/0.20

→ 0.6

ㅤㅤ

→ x = 1600/0.6

→ x = 1000

ㅤㅤ

→ y = 1600 - 1000

→ y = 600

ㅤㅤ

Therefore, 1000 and 600 are the first and second numbers.
