Question

The sum of two number is 20 and their difference is 4 then the greater no. is ______​

Answer 1

Answer:

The greater number is 12

Step-by-step explanation:

Suppose x and y are two numbers

The sum of two numbers is 20

x + y = 20             ..... ( 1 )

Their difference is 04

x - y = 04              ..... ( 2 )

Substituting the values of x from above equations

x + y = 20

4 + y + y = 20

y = 08

Substituting the value of y from above equations

x = 4 + y

x = 12

Thus, the value of two numbers is

x = 12 ,

y = 08

Out of these two numbers 12 is greater

Answer 2

Given: The sum of two number is 20 and their difference is 4.

To find: The greater number

Solution:

• Let the two numbers be x and y.
• According to the question, the sum of x and y is 20.
• So, equation one can be written as,

        $x + y = 20$

• And since their difference is 4, equation two can be written as,

        $x - y = 4$

• On solving these equations the value of x and y are found to be,

        $x = 12$ and $y = 8$

• Here, 12 is greater than 8.

Therefore, the greater number is 12.
