Answer 1

Answer:

C) Rs 5500

Step-by-step explanation:

let principal be Rs. P

A= P+SI

$6600 = p + \frac{p \times r(rate) \times \: t (time)}{100}$

$6600 = p + \: \frac{p \times 20 \times 1}{100}$

6600 = 10P + 2P / 10

6600 = 12P/10

$p = \frac{6600 \times 10}{12}$

P = 1100 × 10

P = 5500 Ans.
