Question

At what rate will the simple interest on rupees 500 amount to rupees 800 in 10 years​

Answer 1

Answer:

SI = 500

Amount = 800

Time = 10 yrs

P = A - SI = 800 - 500 = 300

SI = p*r*t/100

500 = 300 * r * 10 /100

500 = 30 * r

500/30 = r

16.6% = r

Step-by-step explanation:

I= PRT/100

R = 300/50 = 6 %
