The following pie chart shows the data of the number of appeared and passed students of class 12 in sections A,B,C,D,E.
What is the percentage of students who appeared for the exam in section E (correct to one decimal place)?
If \(x - \frac{1}{x} = 6\) , and x > 0, find the value of \(\left( x^2 - \frac{1}{x^2} \right)\)
12\(\sqrt{10}\)
18\(\sqrt{10}\)
24\(\sqrt{2}\)
24\(\sqrt{10}\)
ΔABC ∼ ΔPQR, ar(ABC) = 16 cm² and ar(ΔPQR) = 25 cm². If BC = 20 cm, then QR is equal to:
X, Y and Z completed a work costing ₹3,400. X worked for 5 days, Y for 7 days and Z for 10 days. If their daily wages are in the ratio of 4:5:3, how much amount will be received by X?
If \( (x + \frac{1}{x}) = 3\sqrt{2}, \text{ and } x > 1, \) what is the value of \( (x^{8} - \frac{1}{x^{8}})? \)
