2020 WAEC MATHEMATICS ANSWERS

(1a) Given A={2,4,6,8,…} B={3,6,9,12,…} C={1,2,3,6} U= {1,2,3,4,5,6,7,8,9,10}A’ = {1,3,5,7,9}B’ = {1,2,4,5,7,8,10} C’ = {4,5,7,8,9,10}A’nB’nC’ = {5, 7}(1b) Cost of each premiere ticket = $18.50At bulk purchase, cost of each = $80.00/50 = $16.00Amount saved = $18.50 – $16.00=$2.50

(2ai)
P = (rk/Q – ms)⅔
P^3/2 = rk/Q – ms
rk/Q = P^3/2 + ms
Q= rk/P^3/2 + ms

(2aii)
When P =3, m=15, s=0.2, k=4 and r=10
Q = rk/p^3/2 + ms = 10(4)/(3)^3/2 + (15)(0.2)
= 40/8.196 = 4.88(1dp)

(2b)
x + 2y/5 = x – 2y
Divide both sides by y
X/y + 2/5 = x/y – 2
Cross multiply
5(x/y) – 10 = x/y + 2
5(x/y) – x/y = 2 + 10
4x/y = 12
X/y = 3
X : y = 3 : 1

(5a)
Total income = 32+m+25+40+28+45
=170+m
PR(²)=m/170+m = 0.15/1
M=0.15(170+m)
M=25.5+0.15m
0.85m/0.85=25.5/0.85
M=30

(5b)
Total outcome = 170 + 30 = 200

(5c)
PR(even numbers) = 30+40+50/200
=115/200 = 23/40
