4. Sum of two numbers is 95. If one exceeds the other by 15, find the numbers.
Assume one number to be x. Then the other number will be x + 15.
Now it is given that sum of the two numbers is 95.
Thus quation becomes x + x + 15 = 95
or 2x +15 = 95
Transposing 15 to the RHS, it becomes
2x = 95 - 15 = 80
Dividng both sides by 2, we get
Thus two numbers are 40 and 55
