20
Correct answer is B
Let the number of students that speak Hausa and Igbo be represented by H and I respectively.
n(H only) = 80 - 9 = 71.
n(I only) = 20 - 9 = 11.
n(neither H nor I) = 100 - (71 + 9 + 11)
= 100 - 91 = 9 students.
(p, o, u, r)
(s, p, d, r)
(s, p, n, e)
(n, d, u)
Correct answer is C
\(Y \cup Z\) = \({s, e, n, o, u, p, r}\)
\(X \cap (Y \cup Z)\) = \({p, e, n}\)
Find the simple interest rate percent per annum at which N1,000 accumulates to N1,240 in 3 years
6%
8%
10%
12%
Correct answer is B
1 = \(\frac{PRT}{100}\)
1 = 1240 - 1000
= 240
R = \(\frac{240 \times 100}{100 \times 3}\)%
= 8%
Simplify \(\frac{2\sqrt{3} + 3\sqrt{5}}{3\sqrt{5} - 2\sqrt{3}}\)
\(\frac{19 + 4\sqrt{25}}{11}\)
\(\frac{19 + 4\sqrt{15}}{11}\)
\(\frac{19 + 2\sqrt{15}}{11}\)
\(\frac{19 + 2\sqrt{15}}{19}\)
Correct answer is B
\(\frac{(2\sqrt{3} + 3\sqrt{5})(3\sqrt{5} + 2\sqrt{3})}{(3\sqrt{5} - 2\sqrt{3})(3\sqrt{5} - 2\sqrt{3})}\)
= \(\frac{5 + 12\sqrt{15}}{33}\)
=\(\frac{19 + 4\sqrt{15}}{11}\)
If 8\(\frac{x}{2}\) = (2\(\frac{3}{8}\))(4\(\frac{3}{4}\)), find x
\(\frac{3}{8}\)
\(\frac{3}{4}\)
\(\frac{4}{5}\)
\(\frac{5}{4}\)
Correct answer is D
8\(\frac{x}{2}\) = 2\(\frac{3}{8}\)22 x \(\frac{3}{4}\) 2\(\frac{3x}{2}\)
= 2\(\frac{3}{4}\) \(\frac{3x}{2}\)
= \(\frac{15}{8}\)
\(\frac{2 \times 15}{3 \times 8}\) = \(\frac{5}{4}\)
