Question : What is the total surface area of a solid right circular cylinder of radius 7 cm and height 8 cm?$(\pi=\frac{22}{7})$
Option 1: 560 cm2
Option 2: 660 cm2
Option 3: 850 cm2
Option 4: 760 cm2
Correct Answer: 660 cm2
Solution : Radius = 7 cm Height = 8 cm $\therefore$ The total surface area of a cylinder = $2\pi r(h +r)$ = $2\times \frac{22}{7}\times 7(7+8)$ = $44\times 15$ = 660 cm2 Hence, the correct answer is 660 cm2.

Question : Study the pie chart and answer the question.
The total number of employees of the company in offices C and D exceeds the number of employees in office B by x, where x lies between:
Option 1: 720 and 740
Option 2: 680 and 700
Option 3: 700 and 720
Option 4: 740 and 760
Correct Answer: 720 and 740
Solution : Total number of employees of the company in offices C and D = $\frac{54 + 57.6}{360}×9200$ = 2852 Number of employees in office B = $\frac{82.8}{360}×9200$ = 2116 Required difference = 2852 – 2116 = 736 736 lies between 720 and 740. Hence,
Question : $(1-\frac{1}{5})(1-\frac{1}{6})(1-\frac{1}{7}).......(1-\frac{1}{100})$ is equal to:
Option 1: $0$
Option 2: $\frac{1}{25}$
Option 3: $\frac{1}{100}$
Option 4: $\frac{1}{50}$
Correct Answer: $\frac{1}{25}$
Solution : $(1-\frac{1}{5})(1-\frac{1}{6})(1-\frac{1}{7}).......(1-\frac{1}{100})$ = $(\frac{4}{5})(\frac{5}{6})(\frac{6}{7}).......(\frac{99}{100})$ Notice that the denominator of the first term cancels the numerator of the second term. So, $(\frac{4}{5})(\frac{5}{6})(\frac{6}{7}).......(\frac{99}{100})$ = $\frac{4}{100}$ = $\frac{1}{25}$ Hence, the correct answer is $\frac{1}{25}$.
