Answer 2

Consumed unit of Baisakh = (1250 - 1050) units = Rs. 7.30

Minimum charge up to 20 units = Rs. 80

Additional unit = (200 - 20) = 180 units

Charged of additional units = 180 * Rs. 7.30 = Rs. 1314

∴Total charge = Rs. 80 + Rs. 1314 = Rs. 1394 ans.



2.

Total units consumed = (1250 - 1050) units = 200 units

Here, minimum charge for the first 20 units = Rs. 60

Now, remaining units = 200 - 20 = 180 units

Charge of 180 units = 5.1 * 180 = Rs. 918

Hence, total charge = 60 + Rs. 918 = Rs. 978 ans.
