By selling an article at \(\frac{7}{2}\) of its cost price, a man loses 16%. If he sells it at 90% of its original selling price, then what will be the profit percentage?
If \(x^{2}-5\sqrt{2}\,x-1=0\), then what will be the value of \(x^{3}-\frac{1}{x^{3}}\) ?
\(250\sqrt{2}\)
\(255\sqrt{2}\)
\(485\sqrt{2}\)
\(265\sqrt{2}\)
Study the given graph and answer the question that follows.
In 2019, if the production of vehicles of type A increased by the same percentage as that in 2018, over its previous year, then what was the number (in thousands) of vehicles of type A produced in 2019?
Study the given graph which shows the target and actual production of ACs (in thousands) of a factory over five months and answer the question that follows.
The actual production of ACs in February is what per cent less than the average target production of ACs over the period of five months (correct to the nearest integer)?
If sinθ =\(\sin\theta=\dfrac{2\sqrt{ab}}{a+b}\) , a > b > 0, then the value of \(\dfrac{\cos\theta+1}{\cos\theta-1}\) will be:
\(-\frac{b}{a}\)
\(-\frac{a}{b}\)
\(\frac{a}{b}\)
\(\frac{b}{a}\)
