Question : 1
Find the sum of the following : $1/9 + 1/6 + 1/12 + 1/20 + 1/30 + 1/42 + 1/56 + 1/72$
a) $1/{2520}$

Question : 2
If $50/\text"*" = \text"*"/{12{1/2}}$, then the value of * is :
a) 25
b) $25/2$
c) 4
d) $4/25$
Answer »Answer: (a)
Let the value of * be x.
$50/x = x/{12{1/2}}$
$50/x = {2x}/25$
$2x^2$ = 50 × 25
$x^2$ = 25 × 25 ⇒ x = 25
Question : 3
$9/20 - [1/5 + (1/4 + (5/6 - \ov{1/3 + 1/2}))]$ is equal to
a) $9/10$
b) 0
c) $9/20$
d) 1
Answer »Answer: (b)
Using Rule 1,
$9/20 - [1/5 + (1/4 + (5/6 - \ov{1/3 + 1/2}))]$
= $9/20 - [1/5 + (1/4 + (5/6 - 5/6))]$
= $9/20 - [1/5 +1/4] = 9/20 - 9/20 = 0$
Question : 4
${0.8\ov{3} ÷ 7.5}/{2.3\ov{21} - 0.0\ov{98}}$ is equal to
a) 0.05
b) 0.6
c) 0.06
d) 0.1
Answer »Answer: (a)
${0.8\ov{3} ÷ 7.5}/{2.3\ov{21} - 0.0\ov{98}} = {{{83 - 8}/90} ÷ {7.5}}/{2{{321 - 3}/990} - {98/990}}$
= ${{75/90} + {7.5}}/{{{2}318/990} - 98/990} = {{75/90} + {7.5}}/{{2}220/990}$
= ${7.5}/{90 × {7.5}} × 990/2200 = 1/20 = 0.05$
Question : 5
When simplified, the expression $(100)^{1/2} × (0.001)^{1/3} - (0.0016)^{1/4} × 3^{0} + (5/4)^{- 1}$ is equal to:
a) 0
b) 1.6
c) 1.0
d) 0.8
Answer »Answer: (b)
Using Rule 1,
$(100)^{1/2} × (0.001)^{1/3} - (0.0016)^{1/4} × 3^{0} + (5/4)^{- 1}$
=10 × 0.1 - 0.2 × 1 + $4/5$
= 1 - 0.2 + 0.8 = 1.6
Question : 6
The value of 25 - 5 [2 + 3 (2 - 2 (5 - 3) + 5) - 10] ÷ 4 is :
a) 25
b) 5
c) 23.75
d) 23.25
Answer »Answer: (c)
Using Rule 1,
Expression
= 25 - 5 [2 + 3 {2 - 2(5 - 3) + 5} - 10] ÷ 4
= 25 - 5 [2 + 3 {2 - 2 × 2 + 5} - 10] ÷ 4
= 25 - 5 [2 + 9 - 10] ÷ 4
= 25 - 5 ÷ 4 = 25 - $5/4$
= ${100 - 5}/4 = 95/4 = 23.75$
