Answer 2

Answer:

⇒ Principal = Rs. 5000

Step-by-step explanation:

Amount = Rs. 6600

Rate of Interest = 8%

                          = 0.08

Time = 4 years

Amount = Simple Interest + Principal

⇒ Simple Interest = Amount - Principal

Also, Simple Interest = Principal × Rate × Time

So, Amount - Principal = Principal × Rate × Time

⇒ Amount = Principal + Principal × Rate × Time

⇒ Amount = Principal(1 + Rate × Time)

⇒ 6600 = Principal( 1 + 0.08 × 4)

⇒ Principal × 1.32 = 6600

⇒ Principal = Rs. 5000
