‘Bill Discount’ is a settlement of the bill, where your electricity bill or gas bill is sold to a bank for early payment at less than the face value and the bank will recover the full amount of the bill from you before bill due date. For example, electricity bill for XYZ is $1000; the electricity bill company will sell the bill to the bank for 10% to 20% discount to the face value. Here, the bank will buy the electricity bill for $900 whose face value is $1000, now the bank will recover, full amount of bill from the customer i.e $1000. If the customer fails to pay the bill, the bank will put interest on the outstanding bill and ask the customer for the payment.

The problem of pumping out water from the flooded mines provided the need of self-working engine, which led James Watt to invent the same.
Thus, both A and R are true & R correctly explains A.

Let the required height of the building be x meter

More shadow length, More height(direct proportion)

Hence we can write as

(shadow length) 40.25 : 28.75 :: 17.5 : x
⇒ 40.25 × x = 28.75 × 17.5
⇒ x = 28.75 × 17.5/40.25
= 2875 × 175/40250
= 2875 × 7/1610
= 2875/230
= 575/46
= 12.5 cm

The Bug Tracking System role is discussed below:

- Testers and developers can know the status of the bug at every stage.

- Changes to the Status will be available to all team members.

- Developers and Testers can easily interact with bugs.
