What is the value of x, if it is 2% of the fourth proportional to 6, 7 and 36?
Solution
Correct Answer: Option C
Let the fourth proportional to 6, 7 and 36 be a
\(\begin{array}{l} \Rightarrow \frac{6}{7} = \frac{{36}}{a}\\ \Rightarrow a = \frac{{7 \times 36}}{6}\\ \Rightarrow a = 42\\ \Rightarrow x = \frac{2}{{100}} \times 42 = \frac{{84}}{{100}} = 0.84 \end{array}\)
Hence, x = 0.84
