Answer: (d)D.

330

Why this answer is correct

Given data:

Discount percentage = 20%

Discount amount = Rs.66

Concept:

To find the original bill amount, we can use the formula: Original Bill Amount = (Discount Amount / Discount Percentage).

Calculation:

⇒ Discount Percentage in decimal = 20% = 20/100 = 0.2

⇒ Original Bill Amount = Discount Amount / Discount Percentage

⇒ Original Bill Amount = Rs.66 / 0.2

⇒ Original Bill Amount = Rs.330

Therefore, the electricity bill was Rs.330.

The fraction that we are looking for must satisfy the following equation:

(3/4) = (27/64) * x

Solving for x, we get:

x = (3/4) / (27/64) = (3/4) * (64/27) = 9/16

Therefore, the answer is option 3) 9/16.

425

Why this answer is correct

Solution:

We are given that the simple interest is 136 rupees and the annual rate of interest is 8%. We need to determine the principal amount.

136 = (P * 8 * 4) / 100

P = 425

Therefore, the principal amount is 425 rupees.
