Answer 2

Answer: 15

Given :-

The sum of two numbers is 80.

If the larger number exceeds four times the smaller number by 5.

To Find: Smaller Number

Solution :-

Let the larger number be x and the smaller number be y.  

According to the question,  

x + y = 80…(i)  

x = 4y + 5  

» x – 4y = 5...(ii)  

Subtracting (ii) from (i), we get  

» 5y = 75  

» y = 75/5

» y = 15  

Putting y value in Eq (i)

» x + y = 80

» x + 15 = 80

» x = 80 - 15  

» x = 65  

Hence, the numbers are 65 and 15.

We're told to find smaller number.

Thus, Answer: 15
