In Mrs. Pinto’s flat there are 6 bulbs of 100 W each, a heater of 2 kW and 5 fans of 50W each. If these are used everyday as shown below, calculate the cost of energy consumption for a month of 30 days at the rate of Rs.3.50 per kW h. 6 bulbs of 100 W each used 8 h per day 1 heater of 2 kW used half hour daily 5 fans of 50 W each are used 6 h everyday.

The power of a water pump is 2 kW. If g = 10 m//s^2, the amount of water it can raise in 1 min to a height of 10 m is :
