Answer 1

Hey here is your answer

Your question is :-

Sanjay borrowed 20000 rupees from Punjab National Bank for 1 year 6 month to buy a second hand computer if the rate of interest is 12% per annum calculate the compound interest he has to be at the end of 1 year 6 months.

your answer is :-

principle = 20,000 rs.
time = 1 year and 6 months or 1.5 years
rate = 12 % per year

To find :- amount

C.I. - Amount (for 1 year) = P ( 1 + R/100 )^t

= 20000 (1 + 12/100)^1

= 20000 × 1 + 3/25

= 20000 × 28/25

= 22400 Rs

Interest = Amount - Principle

22400 - 20000

2400 rs.

Interest for 1/2 year =  PRT/100

2400 × 12 × 1 / 2 × 100

144 Rs

Total interest = 2400 + 144

= 2544 Rs.

So ,

amount = interest + principle

2544 rs. + 20000 rs.

22544 rs.
