Question

1. Find the simple interest and amount when :
(i) principal Rs 800, rate = 6% p.a. and time
6% p.a. and time = 3 years​

Answer 1

Given

• Principal = Rs.800
• Rate = 6%
• Time = 3 years

Find out

• Find the simple interest and amount

Solution

$\implies\tt Simple\:Interest=\dfrac{P\times{R}\times{T}}{100} \\ \\ \\ \implies\tt S.I=\dfrac{800\times{6}\times{3}}{100} \\ \\ \\ \implies\tt S.I=\cancel\dfrac{14,400}{100} \\ \\ \\ \implies\tt S.I = Rs.144$

Hence, Simple Interest is Rs.144

Amount = Principal + Simple interest

Amount = 800 + 144

Amount = Rs.944

Answer 2

Answer:

SI = ₹144 and Amount = ₹944

Step-by-step explanation:

Here,

P = ₹800

R = 6℅ p.a.

T = 3 yrs

S.I. = ( P×R×T )/ 100

= ( 800 × 6 × 3 ) / 100

= ₹ 144

Amount = P + S.I.

= 800 + 144

= ₹ 944

Hence,

SI = ₹144 and Amount = ₹944
