Simplify \(6\frac{1}{12} − 2 ¾ + 1 ½ \)
\( 3 \frac{5}{6}\)
\( 4 \frac{5}{6}\)
\( 2 \frac{1}{6}\)
\( \frac{1}{3} \)
Correct answer is B
6½ − 2¾ + 1½
73/12 − 11/4 + 3/2
[(73 − 33 + 18) ÷ (12)]
58/12
29/6
\( 4\frac{5}{6}\)
A man bought a car for N800 and sold it for N520. Find his loss per cent
15%
25%
35%
10%
Correct answer is C
Percentage Loss = (actual loss ) ÷ (Cost price) × 100 Actual loss = Cost Price − Selling Price (sold price) = N800 − N520 = N280 Percentage loss = (280 ÷ 800) × 100 = 35% ∴ His loss percent = 35%
x6 = 123.346
x6 = 424.56
x6 = 122.436
x6 = 124.456
Correct answer is B
(159.75)10 = (y)6
\( \begin{array}{c|c}
6 & 159 \\
\hline
6 & 26 \text{ rem 3} \\
6 & 4 \text{ rem 2} \\
& 0 \text{ rem 4} \\
\end{array}\uparrow \)
15910 = 4236
Then Convert 0.75 to base 6
0.75 x 6 =4.5 i.e 4.5 - 3.00 = 1.5
0.5 x 6 = 3.00 423 + 1.5 =424.5
159.75 = (424.5)6
(159)10 = (424.5)6
\( \frac{2}{15} \)
\( \frac{3}{4} \)
\( \frac{9}{15} \)
\( \frac{1}{15} \)
Correct answer is C

The volume of a cylinder whose height is 4cm and whose radius 5cm is equal to (π = 3.14)
3.13cm2
145cm2
314cm2
214cm2
Correct answer is C
“Explanation
V = πr2h
V = ?, h = 4cm, r = 5cm
V = 3.14(5)2 (4)
V = 3.14(25)(4)
V = 3.14 × 1200
= 314cm2
