Q. The sum of two numbers is 27 and product is 182. The numbers are:10 and 1518 and 1412 and 1511 and 24
Denote numbers x and y: Let's denote the two numbers as x and y. According to the problem, we have two equations:1) x+y=27 (Sum of the two numbers)2) xy=182 (Product of the two numbers)We need to find the values of x and y that satisfy both equations.
Express y in terms of x: We can express y in terms of x using the first equation: y=27−x.
Substitute y into second equation: Now we substitute y=27−x into the second equation to find x:x(27−x)=182Expanding this, we get:27x−x2=182
Rearrange to form quadratic equation: Rearrange the equation to form a quadratic equation:x2−27x+182=0
Factor quadratic equation: We can factor this quadratic equation to find the values of x:(x−14)(x−13)=0
Find possible values for x: Setting each factor equal to zero gives us the possible values for x:x−14=0 or x−13=0So, x=14 or x=13
Calculate corresponding values for y: If x=14, then y=27−x=27−14=13. If x=13, then y=27−x=27−13=14.
Check product for both pairs: We check the product for both pairs to ensure there's no math error:For x=14 and y=13: 14×13=182For x=13 and y=14: 13×14=182Both pairs give the correct product, so there is no math error.
