Question

the sum of two number is 40 and than the difference between them is 14 then the number will be​

Answer 1

Answer: LET the nos be a and b

a+b=40

a-b= 14

2a= 54

a =27

if a =27 THEN b =41

Answer 2

Given -

• Sum of two numbers = 40
• Difference of two numbers = 14

⠀

To find -

• The numbers.

⠀

Solution -

Firstly,

• Let the first number be x.
• Let the second number be y.

⠀

According to the question

⇢ Sum of numbers = 40

⇢ x + y = 40⠀⠀...[1]

⠀

⇢ Difference of numbers = 14

⇢ x - y = 14⠀⠀...[2]

⠀

Subtracting [2] from [1]

➝ (x + y) - (x - y) = 40 - 14

➝ x + y - x + y = 26

➝ x - x + y + y = 26

➝ 2y = 26

➝ y = 13

⠀

Putting the value of y in [1]

➝ x + 13 = 40

➝ x = 40 - 13

➝ x = 27

⠀

Hence,

• First number = x = 27
• Second number = y = 13
