Your bookkeeper extracted a trial balance on 31 December 2016 which failed to agree by £860, a shortage on the credit side of the trial balance. A suspense account was opened for the difference.

In January 2017 the following errors made in 2012 were found:

(1) Sales day book had been undercast by £1,205.

(2) Sales of £980 to I. Blane had been debited in error to I. Blank's account.

(3) Rent account had been undercast by £404.

(4) Discounts allowed account had been overcast by £59.

(5) The sale of a computer at net book value had been credited in error to the Sales account £200.

You are required to:

(a) Show the journal entries necessary to correct the errors.

(b) Draw up the suspense account after the errors described have been corrected.

(c) If the net profit had previously been calculated at £58,600 for the year ending 31 December 2016, show the calculations of the corrected net profit.
