5.Sum of two numbers is 95. If one exceeds the other by 3, find the numbers. |
|
Answer» Answer: Let the ONE number be x and the other number be y. It is given that the sum of the numbers is 95, therefore, we have: x+y=95....(1) It is also given that one number exceeds the other by 3 which MEANS: x=y+3 ⇒x−y=3....(2) Now, we add equations 1 and 2 as follows: x+y+x−y=95+3 ⇒(x+x)+(y−y)=98 ⇒2x=98 ⇒x= 2 98
⇒x=49 Now, substitute the value of x in EQUATION 2 to find the value of y as shown below: x−y=3 ⇒49−y=3 ⇒y=49−3 ⇒y=46 Therefore, the two numbers are x=49 and y=46 and the product of the numbers is: x×y=49×46=2254. Hence, the product of the numbers is 2254 |
