MATHEMATICS

1. A group of market women sell at least one of yam, plantain and maize. 12 of them sell maize, 10 sell yam and 14 sell plantain. 5 sell plantain and maize, 4 sell yam and maize, 2 sell yam and plantain only while 3 sell all the three items. How many women are in the group?

A. 25
B. 19
C. 18
D. 17
Answer: A
Explanation
Let the three items be M, Y and P.
n{M ∩ Y} only = 4-3 = 1
n{M ∩ P) only = 5-3 = 2
n{ Y ∩ P} only = 2
n{M} only = 12-(1+3+2) = 6
n{Y} only = 10-(1+2+3) = 4
n{P} only = 14-(2+3+2) = 7
n{M∩P∩Y} = 3
A number of women in the group = 6+4+7+(1+2+2+3) as above =25 women.

2. If log 10 to base 8 = X, evaluate log 5 to base 8 in terms of X.

A. 12
X
B. X-14
C. X-13
D. X-12
Answer: C
Explanation
log810
= X = log82x5
log82
+ log85
= X
Base 8 can be written as 23
log82=y
therefore 2=8y
y=13
13=log82
taking 13
to the other side of the original equation
log85=X−13

3. Find the value of X if 2√x+2√=1x−2√
A. 3√2+4
B. 3√2-4
C. 3-2√2
D. 4+2√2
Answer: A
Explanation
Start your solution by cross-multiplying,
2√x+2√=1x−2√
[x – √2] √2 = x + √2
where √2×√2=2
x√2 – √2 * √2 = x + √2
then collect like terms
x√2 – x = √2 + 2
and factorize accordingly to get the unknown.
x(√2 – 1) = √2 + 2
x = √2+2√2−1
rationalize

x = √2+2√2−1
* √2+1√2+1
x = √4+√2+2√2+2√4+√2−√2−1
x = 2+3√2+22−1
x = 3√2+41
x = 3√2 + 4

4. If (a2b−3c)34a−1b4c5=apbqcr
What is the value of p+2q?
A. (5/2)
B. -(5/4)
C. -(25/4)
D. -10
Answer: D
Explanation
Hint: apply basic mathematics rules beginning from BODMAS to algebra, and follow solution carefully to arrive at
p = 52
, q = -254
and r = -174
NUMERATOR: a21∗34
b−31∗34
c11∗34
a32
b−94
c34
Using index method for numerator & denominator : a32−−11
b−94−41
c34−51
: a52
b−254
c−174
Then p+2q will give you 52+2(−254)=−10

5. If a2b−3c3/4a−1b4c5
= apbqcr
what is the value of p+2q?
A. (5/2)
B. -(5/4)
C. -(25/4)
D. -10
Answer: D
Explanation
Hint: Use BODMAS and algebra to arrive at the values of P = 5/2, q = -25/4 and r = -9/2.
Then substitute the values of p and q into p+2q to get -10.
