Question

answer this i will mark you as
find the rate of interest
p= rs 3520
t=2.5 years
i= rs 792
find the time of following cases
p=rs 9200
r=12.5% per year
i=rs 2875

Answer 1

Step-by-step explanation:

i) si=792

p=3520

t=2.5

si=prt/100

792=3520*25*r/1000

R=792*1000/3520*25

R=7,92,000/88,000

R=8%

ii) p=9200

r=12.5%

SI=2875

PRT/100

2875=9200*125*t/1000

t=2875*1000/9200*125

t=2,875,000/1,150,000

t=2.5years
