Correct Answer: 0.5

Solution : Given: The value of the ratio $\frac{b}{a}=0.7$.
The value of the expression $\frac{a–b}{a+b}+\frac{11}{34}$ is given as,
$=\frac{1–\frac{b}{a}}{1+\frac{b}{a}}+\frac{11}{34}$
Substitute the value of $\frac{b}{a}=0.7$ in the above expression,
$=\frac{1–0.7}{1+0.7}+\frac{11}{34}$
$=\frac{0.3}{1.7}+\frac{11}{34}$
$=0.17+0.33=0.5$
Hence, the correct answer is 0.5.

Correct Answer: 54°

Solution : Given percentage of B = 15%
The central angle will be 15% of the 360°
$= \frac{15}{100}\times 360° = 54°$
Hence, the correct answer is 54°.

Correct Answer: 0.16

Solution : Given: The sum of the first 20 terms of the series $\frac{1}{5×6}+\frac{1}{6×7}+\frac{1}{7×8}+....$
So, $a_{1} =5$ and $a_{20} =5+(20-1)×1=24$
20^th term $=\frac{1}{24×25}$
$=\frac{1}{5×6}+\frac{1}{6×7}+\frac{1}{7×8}+.... + \frac{1}{24×25}$
$=\frac{1}{5}-\frac{1}{6} + \frac {1}{6} - \frac{1}{7}+\frac{1}{7}-\frac{1}{8}+..............+\frac{1}{24}-\frac{1}{25}$
$=\frac{1}{5}-\frac{1}{25}$
$=\frac{4}{25}$
$= 0.16$
Hence, the correct answer is 0.16.

Correct Answer: Sludge

Solution : The correct option is Sludge.

Sludge is a byproduct of sewage treatment that may be degraded to generate biogas through a biological process known as anaerobic digestion. Anaerobic digestion is the breakdown of organic materials by microbes in the absence of oxygen. In the case
