Option 1: 560 cm2

Option 2: 660 cm2

Option 3: 850 cm2

Option 4: 760 cm2

Team Careers360 11th Jan, 2024

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 : $(1-\frac{1}{5})(1-\frac{1}{6})(1-\frac{1}{7}).......(1-\frac{1}{100})$ is equal to:

Option 1: $0$

Option 2: $\frac{1}{25}$

Option 3: $\frac{1}{100}$

Option 4: $\frac{1}{50}$

Team Careers360 4th Jan, 2024

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 $\frac{1}{25}$.
