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
= 65124
