Question

At what rate percent per Annum will the simple interest on 7500 be rs. 650 in 8 months

Answer 1

P = Principal Amount = 7500

SI = Simple Interest = 650

T = Time = 8 months = 8months / 12 months = 0.67 year

R =Rate of Interest Per Annum= ?

SI = PTR/100

650 = 7500×0.67×R/100

650 × 100 = 7500 × 0.67 × R

65000 = 5025 × R

65000/5025 = R

13% = R = Rate of Interest Per Annum

Answer 2

Answer:

pnr/100 formula

principal amount P -7500

simple interest SI- 650

time period T - 8 month

interest n-?

Step-by-step explanation:

time of period to be change per year so one year 12 month given time 8 month

now 8/12=0.6667

SI= PNR/100

650=7500*(8/12)*R/100

R=650*100/7500*0.67

R=65000/7500*0.67

R=650/75*0.67

R=12.93%

r= 13%
