Question

find the simple interest when principal is ₹ 600 rate 2% p. a. and time is 20 months. ​

Answer 1

Given :

• Principal = ₹600
• Rate = 2% p.a.
• Time = 20 months

To find :

Simple interest

Formula used :

I = Prt

Here,

• I = Simple interest
• P = principal
• r = rate
• t = time

Solution :

First of all we need to convert given time into years.

We know that 12 month make a year.

➝ 12 month = 1 year

➝ 1 month = (1/12) year

➝ 20 months = (20/12) year

_______________________________________________

$\sf \implies\: I \:=\:600 \times \dfrac{2}{100} \times \dfrac{20}{12} \\ \\ \sf \implies\: I \: = \: \dfrac{6 \times 2 \times 20}{12} \\ \\ \sf \implies\: I \:=\:20$

ANSWER :

Answer 2

Answer:

Principal = Rs.600

Rate = 2 % per annum

Time = 20 months

Therefore,

Simple Interest = Principal × Rate × Time

100

Simple Interest = 600 × 2 × 20

100

Simple Interest = 24000

100

Simple Interest = 240 Ans.
