Question

find the sum of which different between the simple interest and the compound interest at the rate 10% per annum compounded annually be rupees 64in 2 years​

Answer 1

Step-by-step explanation:

Rs. 10,000

Let the sum be Rs.P

Time =2year

Rate=8%

S.I for 2 years=

P×8×2/100= 4P/25

C.I for 2 years=[P(1+ 8/100) 2 ]−P

⇒[P× 108/100 × 108/100]−P

⇒ 729/625 P −P= 104/625P

According to the question

⇒ 104/625P− 25

4P=64⇒ 625

104P−100P/625=64

⇒4P=64×625

⇒P= 464×625

=Rs.10000
