Question

plz solve question number 8 fast ​

Answer 1

Step-by-step explanation:

p=8000. R=10

N=2

A=?

A=p(1+R/100)n

=8000(1+10/100)2(0 and 0 get cancel)

=8000(11/10)2

=8000(11/10)(11/10)

=9680

compound interest=A-P

=9680-8000

=1680

FOR HALF YEAR=1680/2=840

Answer 2

Answer:  Step-by-step explanation: half yearly is 6/12=1/2 principal amount(p)=8000*1/2=Rs.4000 rate of interest(r)=10*1/2=5% number of years(n)=2*1/2=1 formula for amount =p[1+r/100]^n                                    =4000[1+5/100]^1                                    =4000[1+1/20]^1                                    =4000*21/20                                    =₹4200 C.I=Amount- P      =4200-4000=₹200 HOPE THIS HELPS  PLZ MARK AS BRAINLIEST
