A house is fitted with seven tubelights of rating 220 V, 40 W each , two bulbs of rating 220 V, 60 W each, five fans each drawing a current of 0.4 at 220 V , and a heater of resistance 48.4 Omega . The main line power supplied to the house is at 220 V . Calculate the bill for the month of january if tubelights and bulbs are used for 6 h daily, fans for 1 h daily , and heater for 10 h daily. The electricity is to cost Rs. 2 per unit.

A thermal power plant produed electric power of 600kW at 4000V, which is to be transported to a place 20 km away form the power plant for consumer's usage. It can be transported either directly with a cable of large current carrying capacity or by sing a combination of step-up and step-down transfprmers at the two ends. THe drawback of the direct transmission is the large energy dissipation. In the method wsing transformers, the dissipatiion is much smaller. In this method a step-up transformers is used at the plant side so that the current is reduced to a smaller value. At the consumers'end, a step-down transformer is used to supply power to the consumers at the specified lower voltage. It is reasonable to assume that the power cable is purely resostive and the transformers are ideal with power factor unity. All the currents and voltagementioned are values. If hte direct transmission method with a cable of resistance 0.4(omega) km^(-1) is used, the power dissipation (in %) during transmission is

The principle of 'equity today does not apply to wages alone. Value to the customer, care for the environment, dealings with business associates would all come under the purview of this principle. Today, we find that Public Sector Undertakings (PSUs) have developed entire townships as, for example, BHEL has developed Ranipur in Herdwar (Uttaranchat). Similarly, Shri Mahila Griha Udyog Lijjat Papad is famous for its quality Papad throughout the world. The organisation which started with a modest loan of Rs. 80 now has a turnover of over Rs. 301 crorr. Its exports exceed Rs. 10 crore. The company has at least 61 branches. The company is synthesis of three core value (or concepts), namely the concept of business, the concept of family and the concept of devotion. All its dealings are carried ot on a sound and pragmatic footing-production of quality goods and at reasonable prices. Besides, its member-sisters donate collectively for good cause from time-to-time according to their capacity. All the affairs of the institution are dealt with in a manner similar to that of a family carrying out its own daily household chores. For the member-sisters employees and well-wishers, the institution is never merely a place to earn one's livelihood-it is a place of worship to devote one's energy not for his or her own benefits but for the benefit of all. In this institution workship. The institution is open to everybody who has faith in its basic concepts. (a) To what aspect of the significance of principles of management would you attribute the endeavours of BHEL and Shri Mahila Griha Lijjat Papad ? (b) Explain any four other points of significance of principles of management.

In a house there are ten 60-watt lamps. Three 40-watt flourorescent tubes and three 40-watt fans. When all these are switched on what is the current drawn from the mains if the supply voltage is 220V? Calculate the power drawn and the cost for using them for 6hours daily in a month of 30 days.( 1 B.O.T. unit costs 30 pasise).
