Question

find the amount and the compound interest if principal=Rs.5000,Rate of interest=5p.c.p.a. Duration=3 years​

Answer 1

Answer:

A = ₹ 5788.125 ; CI = ₹ 788.125

Step-by-step explanation:

A = P [1 + R/100] ^N

= 5000 [1 + 5/100]^3

= 5000 [105/100]^3

= 5000×105/100×105/100×105/100

= 5×105×105×105/1000

= 525×11025/1000

= 5788125/1000

= 5788.125 rs

CI = A - P

= 5788.125 - 5000

CI = 788.125 rs

Answer 2

Answer:

Given:

Principal = Rs. 5000

Rate = 5%

Time = 3 years

Formula used:

In case of simple interest

A = P(1 + RT/100)

Where, A = Amount, P = Principal

R = Rate, T = Time

Calculation:

A = P(1 + RT/100)

⇒ A = 5000 × (1 + 15/100)

⇒ A = 5000 × (23/20)

⇒ A = Rs. 5750

∴ The amount is Rs. 5750.
