N676.50
N820
N1,640
N4,920
Correct answer is C
I = N123; R = 3%' T = 2\(\frac{1}{2}\) yrs; P = \(\frac{100 \times 1}{RT}\)
P = \(\frac{100 \times 123}{3 \times 2.5}\)
principal(P) = N1640
What is the place value of 9 in the number 3.0492?
\(\frac{9}{10000}\)
\(\frac{9}{1000}\)
\(\frac{9}{100}\)
\(\frac{9}{10}\)
Correct answer is B
Place value of 9 in 3.0492
= 0.009
= \(\frac{9}{1000}\)
Given that (2x - 1)(x + 5) = 2x2 - mx - 5, what is the value of m
11
5
-9
-10
Correct answer is C
(2x - 1)(x + 5) = 2x2 - mx - 5
2x2 + 10x - x - 5
= 2x2 + 9x - 5 = 2x2 - mx - 5
comparing the co-efficient of x
-m = 9
m = -9
What must be added to x2 - 3x to make it a perfect square?
\(\frac{9}{4}\)
\(\frac{9}{2}\)
6
9
Correct answer is A
x2 - 3x + k(perfect square)
k = (-\(\frac{3}{2}\))2 ; k = \(\frac{9}{4}\)
2
4

25
Correct answer is D
From y = \(\frac{1}{2} \sqrt{x}\)
when y = 2.5 or \(\frac{5}{2}\), x = P
\(\frac{5}{2} \times \frac{1}{2} \sqrt{P}\)
\(\sqrt{P} = \frac{10}{2} = 5\)
P = 52
= 25
