A student multiplied 7236 by 65 instead of multiplying by 56. By how much was his answer greater than the correct answer?
Let us multiply 7236 by 65 and 56 separately and find the solution.
Answer: The student's answer was greater than the correct answer by 65124.
The difference between both the products will give the answer.
Explanation:
The student was supposed to multiply 7236 by 56 but he multiplied it by 65.
7236 × 65 = 470,340 (incorrect multiplication) ------------------- equation (1)
As per the question, the student had to multiply 7236 and 56
7236 × 56 = 405,216 (correct multiplication) --------------------- equation (2)
Difference between the two values are:
equation (1) - equation (2)
470,340 - 405,216 = 65,124
Thus, the student's answer was greater than the correct answer by 65124.
