(a) The rateable value of a house is N5 600 000.00. Calculate the tax paid
if the rate is 20k in the naira.
(b) A married man who has five children
under 16 years of age works with an
oil company and earns N200 000 per
annum. He is allowed the following
tax-free allowances:
10% of his annual salary,
N3000.00 per annum as a married man
N2000.00
per
child
per annum up to a
maximum of 4 children,
N5000.00 per annum for a life insur-
ance policy.
Income tax is charged on the remainder as
follows:
on the first N50 000, 10k per naira
on the next N50 000, 20k per naira
on the rest, 25k per naira.
Calculate his average monthly tax, to the
nearest kobo (WAECIGCE 1982)

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
