Question

p=8000,r=5pcpa,t=?,i=800,a=?​

Answer 1

Answer:

• The time is 2 years.
• And the amount is 8800 Rs.

Step-by-step explanation:

Given:

Principal (p) = 8000 Rs

Rate (r) = 5 pcpa

Interest (I) = 800 Rs

Find: Time (N) and Amount

Formula: Interest (I) $=\frac{PNR}{100}$

Amount = Principal + Interest

Step 1: Find time by using interest.

Interest (I) $=\frac{PNR}{100}$

$800= \frac{8000 \times 5 \times N}{100} \\800 =80 \times 5 \times N\\800 = 400 N\\N = \frac{800}{400} \\N = 2 years$

So, the time is 2 years.

Step 2: Find the amount.

Amount = Principal + Interest

= 8000 + 800

= 8800 Rs.
