Question

If period = 8 yrs, rate = 9 p.c.p.a., interest = 8640 Find the principal?​

Answer 1

Answer:

here is your answer

Step-by-step explanation:

If period = 8 yrs, rate = 9 p.c.p.a., interest = 8640 Find principal

) Principal = Rs 9,000

Rate of interest = 10% p.a.

Number of years = 3 years

Simple Interest =Principal×Rate×Time100=9,000×10×3100= Rs 2700=Principal×Rate×Time100=9,000×10×3100= Rs 2700      

Amount = Principal + Interest = 9,000 + 2,700 = Rs 11,700

∴ The simple interest is Rs 2,700. 

And amount is Rs 11,700.

(2) Principal = Rs 15,000

Rate of interest = 11% p.a.

Number of years = 2 years

Simple Interest=Principal×Rate×Time100=15,000×11×2100= Rs 3300=Principal×Rate×Time100=15,000×11×2100= Rs 3300

Amount = Principal + Interest = 15,000+ 3,300 = Rs 18,300

∴ The simple interest is Rs 3,300.

And amount is Rs 18,300.

Principal = Rs 1,50,000

Rate of interest = 10% p.a.

Number of years = 3 years

Simple Interest =Principal×Rate×Time100=150,000×10×3100= Rs 45000=Principal×Rate×Time100=150,000×10×3100= Rs 45000

Amount = Principal + Interest = 1,50,000 + 45,000 = Rs 1,95,000

∴ The simple interest is Rs 45,000

And amount is Rs 1,95,000.
