According to division algorithm: Dividend = Divisor x Quotient + Remainder
Dividend = 58 x 40 + 31 = 2341.
So 2341 is the required number.
2351
The student incorrectly calculated the division, as the correct quotient of 878 divided by 31 is 28 with a remainder of 10, not 11. This error likely occurred in the subtraction step after multiplying 31 by 28, where she should have subtracted 868 from 878, leading to the correct remainder of 10. Therefore, the student miscalculated the remainder after finding the quotient.
(7 x 4) + 3 = 31
