Two statements are followed by three Conclusions I, II and III. You have to consider the statements to be true, even if they seem to be at variance from commonly known facts. You are to decide which of the given conclusions can definitely be drawn from the given statements and indicate your answer accordingly. Statements: I. Mukesh Ambani overtook Alibaba Group founder Jack Ma to become Asia’s richest person as he positions Reliance Industries Ltd. to disrupt the e-commerce space in India.  II. The chairman of India’s refining-to-telecoms conglomerate, Ambani was estimated to be worth $44.3 billion on Friday with Reliance Industries Ltd. rising 1.6 percent to a record 1,099.8 rupees. Conclusions: I. Ambani, best known for executing large-scale projects, spearheaded construction of the world’s largest refining complex in Jamnagar, owns the most-widespread mobile data network globally and claims to have India’s biggest as well as most-profitable retail firm.  II. Jio is the driver behind the surge in Reliance. Jio will introduce a fiber-based broadband service across 1,100 Indian cities in August in what Ambani said would be the biggest greenfield fixed-line rollout anywhere in the world.  III. If the company is going to double profit a few years down the line, the stock price is also likely to increase.
What approximate value should come in place of the question mark (?) in the following question?  (795.009 ÷ 15.234 + 768.123 ÷ 12.099 + 63.98 ÷ 4 – 1272.985 ÷ 19.195) + (–36.09% of 350 + 16.009 × 22.897) = ?

Consider an NMOS transistor having kn= 2 mA/V2. Let the transistor be biased at VOV = 1V. For operation in saturation, what dc bias current ID results? If a +0.1-V signal is superimposed on VGS, find the corresponding increment in collector current by evaluating the total collector current ID and subtracting the dc bias current ID.
