1. 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 :

• Let us assume, “x” and “y” as first and second numbers.

ㅤㅤ

• Here, we use “x” and “y” as a variables instead of using “First number, Second number” in every equation.

ㅤㅤ

• Using the variables make easier to understand the equation.

ㅤㅤ

• We learn about variables in the chapter “Linear equations and variables“.

ㅤㅤ

• 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
