A student multiplied 78,592 by 65 instead of multiplying by 56-By
hom
much
was his answer greater than the
coverest answey?​

Answer 1

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 2

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
