Question

A student multiplied 5342 by 87 instead of multiplying by 78. By how much was his/her answer greater than the correct answer?​

Answer 1

Answer:

48,078

Step-by-step explanation:

Incorrect product found by the student = 5,342 × 87

                                                                 = 4,64,754

Correct product = 5,342 × 78

                           = 4,16,676

Difference between the two products = 4,64,754 - 4,16,676

                                                               = 48,078

Hope this helps you a lot mate :)

Answer 2

what the student did = 5342 ×87= 464754

what he had to do = 5342 x 78 = 416676

therefore difference between the 2 products = 464754 ‐ 416676 = 48078
