A student was asked to find 5/16 of a number. By mistake he found 5/6 ...
To solve this problem, we need to set up an equation based on the given information.
Let's assume the number we are trying to find is "x".
- First, the student mistakenly found 5/6 of the number instead of 5/16.
- So, the student's answer is (5/6)x.
- The correct answer, which is 5/16 of the number, is (5/16)x.
According to the given information, the student's answer was 250 more than the correct answer. So, we can set up the equation as follows:
(5/6)x = (5/16)x + 250
Now, let's solve this equation to find the value of "x".
Multiplying both sides of the equation by 16 and 6 to eliminate the denominators, we get:
16 * (5/6)x = 6 * (5/16)x + 16 * 250
Simplifying:
(80/6)x = (30/16)x + 4000
Multiplying both sides by 48 to get rid of the fractions:
48 * (80/6)x = 48 * (30/16)x + 48 * 4000
Simplifying:
640x = 90x + 192,000
Now, let's simplify further:
640x - 90x = 192,000
550x = 192,000
Dividing both sides by 550:
x = 192,000 / 550
x ≈ 349.09
Therefore, the given number is approximately 349.09.
Since this number is not one of the options provided, we can conclude that none of the options given are correct.
