Correct answer is C
Let assume the cost price is 100%
Marked up price + cost price = 20 + 100 = 120%
Discount at 20% = 20/100 × 120 % of cost price
Selling price = cost price − gain
= (120 − 24)% of cost price
= 96% of cost price
Loss = (100− 96)% of cost price
= 4% of cost price
∴ He will wake 4% loss

If duty is levied at 25%, find the duty to be added to a bill of N80.
N100
N20
N80
N150
Correct answer is B
25% of N80 = 25/100 × 80
= N20.00
How many sides has a regular polygon whose interior angles are 120°each
4
5
6
3
Correct answer is C
Each exterior angle = 180 − 120=60
Exterior angle =360/n
60 = 360/n
n =360/6
= 6
Solve the equation
\( 5^{(x − 2)} = (1 ÷ 125)^{(x +3)}\)
3/2
− 7/4
4/7
7/4
Correct answer is B
\( 5^{(x − 2)} = (125^{−1} )^{(x + 3)}\\
5^{(x − 2)} = (5− 3)^{x + 3}\\
5^{(x − 2)} = 5^{− 3x − 9}\\
x + 3x = − 9 + 2\\
4x = − 7\\
x = \frac{−7}{4} \)
