Section B
This course provides the
candicates of HKCEE 1979 a
general revision in Mathematics
(Alternate Syllabus B). A
knowledge of mathematics up to
HKCEE is assumed, and the
subject is developed by a
concentric treatment in which
each exercise is used to
illustrate ideas already
treated.
Exercise 1
Attempt All questions in
Section A and any Six questions
in Section
Section A

whose roots are the aquare
12 of the roots of x2-x-5-0. Express your equation in the
form ax+bx+c=0 where a, b
and care integers.
2. Find the value of x if
510gx=1+41og2-10g5

5. One liquid contain a 22}%
the
of water; 'another contains 27% of water. A glass is
filled 5 parts of the first
liquid and 7 parts of the
second. How much precent
of it is water?.
6. Two persons, A and B,
hold
a field in common at a
rental $14400. A puta in 23 horses for 27 dayai
and B. 21 horses for 39 days;
how much of the rent should
be paid by each?
7. In the figure, ABCD is a
parallelogram. DE 2EC.

are drawn out and the cask is then filled up with:
spirit. 12 more litres are withdrawn and the cask is
then filled up with water. What is the final percentage
of water in the cask? 13. In a triangle, the sines of the angles are in the ratio 4:5:6, and the side opposite the smallest angle is 20 cm. Find
(a) the length of the other
two sides
