In which of the following reactors material converted into fissile materials is more than fissile material consumed?

In which of the following reactors material converted into fissile materials is more than fissile material consumed? Correct Answer Breeder reactor

Burner reactor or thermal reactor is designed only to consume fissile materials and to give heat energy. Converter reactor converts fertile material into fissile material but the rate of conversion is slower than rate of conception. Only breeder reactor from above options is such a reactor which converts fertile materials into fissile materials faster than consumption of fissile materials.

The electricity bill of a certain establishment is partly fixed and partly varies with the number of units of electricity consumed. In a certain month when 540 units are consumed, the bill is Rs. 1,800. In another month the consumed units are 620 and the bill is Rs. 2,040. If 500 units of electricity is consumed in a month, the bill for that month is
