## IMPORTED GENERATORS

Q. In view of the increasing power cuts, Chowdhury Nathan Singh had provided four diesel generators to his factory. These were imported from Germany, England, Russia and Japan. They began to produce 300, 40, 600, 700 units of electricity per hour, respectively.

Last Friday there was complete power-failure, as a result of which all the four generators were switched on simultaneously at 1 o’clock. After 4 hours the first generator was switched off. The second was switched off 2 hours later. One hour after this the third generator went out of order and could not be re-started.

Two hours after this the electrical supply commenced and the fourth generators had produced 13,700 units of electricity.

From the above can you tell which generator ran for how many hours and how many units of electricity did each produce?

A.
 Generator producing country Hours in use Electricity produced Germany 6 hrs. 1800 units England 4 hrs. 1600 units Russia 9 hrs. 5400 units Japan 7 hrs. 4900 units

Note:

 Generator/unit Hours 4 6 7 9 Germany 300 1200 1800 2100 2700 England 400 1600 2400 2800 3600 Russia 600 2400 3600 4200 5400 Japan 700 2800 4200 4900 6300

These generators can produce:
Maximum - (1200 + 2400 +4200 + 6300) = 14100 units.
Minimum – (2700 + 2800 + 3600 + 2800) = 11900 units.
