was his answer greater than the
coverest answey?
Answers
Answer:
As per the given conditions
The student had to multiply 7236 by 56
So 7236 x 56 ——(i) which is the correct one
But the student multiplied by 65
Sp 7236 x 65 ———(ii) which is the wrong one
Hence the difference between the correct and the incorrect value can be calculated by subtracting the two above obtained equations (i) and (ii). That is
7236 x 65 – 7236 x 56
Taking out 7236 as the common factor
=7236 (65-56)
=7236 (9)
= 7236 x 9
Answer:
707,328
Step-by-step explanation:
The student's answer after the mistake-
=> 78,592*65
=> 51,08,480
The correct answer-
=> 78,592*56
=>44,01,152
To get by how much his answer was greater than the correct answer, we have to subtract his answer by the correct answer
On subtracting, we get
=> 51,08,480-44,01,152
=> 707,328
His answer was 707,328 greater than the correct answer
