Question : Comprehension: Read the given passage and answer the questions that follow. What if globally designed products could radically change how we work, produce and consume? Several examples across continents show the way we are producing and consuming goods could be improved by relying on globally shared digital resources, such as design, knowledge and software. Imagine a prosthetic hand designed by geographically dispersed communities of scientists, designers and enthusiasts in a collaborative manner via the web. All knowledge and software related to the hand is shared globally as a digital commons. People from all over the world who are connected online and have access to local manufacturing machines (from 3D printing and CNC machines to low-tech crafts and tools) can, ideally with the help of an expert, manufacture a customized hand. This is the case of the Open Bionics project, which produces designs for robotic and bionic devices. There are no patent costs to pay for. Less transportation of materials is needed since a considerable part of the manufacturing takes place locally; maintenance is easier, products are designed to last as long as possible, and costs are thus much lower. Question: Select the most suitable word from the passage which means ‘scattered’.

Question : If $x^2-9x+1=0$, what is the value of $(x^3+\frac{1}{x^3})$?
Option 1: $54$
Option 2: $108$
Option 3: $702$
Option 4: $810$
Correct Answer: $702$
Solution : Given: $x^2-9x+1=0$ Dividing both sides by $x$, we get, $⇒x-9+\frac{1}{x}=0$ $⇒x+\frac{1}{x}=9$ Cubing both sides, we get, $⇒(x+\frac{1}{x})^3=9^3$ $⇒x^3+\frac{1}{x^3}+3×x×\frac{1}{x}(x+\frac{1}{x})=729$ $⇒x^3+\frac{1}{x^3}+3×9=729$ $\therefore x^3+\frac{1}{x^3}=729-27=702$ Hence, the correct answer is $702$.
Question : A vendor bought a book, marked at INR 850 at successive discounts of 20% and 10%, respectively. He spent INR 55 on transport and sold the book for INR 980. What will be his profit percentage (rounded off to 2 decimal places)?
