Answer 1

ANSWER:

• Required numbers are 75 and 30.

GIVEN:

• Sum of two numbers is 105.
• Difference of two numbers is 45.

TO FIND:

• The two numbers.

SOLUTION:

Let the first number be 'x'.

Let the Second number be 'y'.

Where x > y

According to the Question:

CASE 1

=> x+y = 105 ....(i)

CASE 2

=> x-y = 45 .....(ii)

Adding eq (i) and (ii) we get;

=> x+y+x-y = 105+45

=> 2x = 150

=> x = 150/2

=> x = 75.

Putting x = 75 in eq (I)

=> 75+y = 105

=> y = 105-75

=> y = 30

Required numbers are 75 and 30.
