Question

if the compound interest on certain sum for 2years at 10%.per annum is 1050.find sum​

Answer 1

Answer:

Step-by-step explanation:

Amount = Principal (1+Rate\100)^n

Amount = Principal +compound interest

Principal + CI = Principal (1+Rate\100)^n

P+1050 = P(1+10\100)^n = P+1050 = P (110\100)^2

P+1050 = P(110\100) (110\100) = P+1050 = P+1050

= P 121\100 = 100 P +105000 = 121 P

105000= 121 P - 100 P

105000=21 P

P = 105000\21 = 5000

=5000

Therefore, P = Rs. 5000

Answer 2

Answer:

Ur answer is ₹5000

Step-by-step explanation:

A= P(1+r/n)^nt

where A=P + C.I

P is principle amount , C.I is compound interest, r is rate of interest, n is no. of times interest is compounded, t is time period.

P+C.I= P(1+0.1)^2

P+1050=P(1.21)

1050=.21P

P= ₹5000
