please ans fast and correct ​

Answer 1

Answer:

A=10400

R=14%

N=5

SI=PNR/100

SI=P×5×14/100

SI=7P/10

SI=A-P

7P/10=10400-P

7P/10 +P=10400

17P/10=10400

P=104000/17

P=6117.647

AT 8YRS

SI=PNR/100

SI=6117.647×8×14/100

SI=6117.647×112/100

SI=6117.647×1.12

SI=6851. 77(approx)

you will get A=12970
