Question

What sum will Amount to Rs. 6600 in 4 years at 8% per annum simple interest?​

Answer 1

Step-by-step explanation:

SI = ptr

si = 6600 × 4 × 8 / 100

si = 2112

Answer 2

Step-by-step explanation:

p=Principal amount

n=Number of years

r=rate of interest

Total amount=$p+\frac{p*n*r}{100}$

Total amount=6600

n=4 years

r=8% p.a

We have to find the principal amount

⇒6600=+$p+\frac{p*4*8}{100}$

⇒6600=$p+\frac{32p}{100}$

⇒6600=$p+\frac{8p}{25}$

⇒165000=33p

⇒p=5000

hence total amount is 5000
