Answer 1

Answer:

we have P= 10000 R= ? T= 3 Years

Step-by-step explanation:

we have  SI = A-P= 11200-10000= 1200

R = SI *100/P×T i.e 1200×100/10000×3= 4%

P=10000 R= 4% T=3 years

SI = PRT/100= 11200×4×3/100= 1344

A=P+ SI= 11200+1344 =12544

P =12544 R=4% T= 3 years

SI=PRT/100 = 12544×4×3/100=1505·28.
