You pawn a guitar and receive $880. One month later, you get the guitar back by paying $1250. If this is simple interest, then w

Lemur [1.5K]

Interest=1250-880=370
I=PRT
P=principal
r=rate in deicmal
t=time in years

1 month so t=1/12
P=880
I=370

370=880*r*1/12
370=220/3r
times both sides by 3
1110=220r
divdie both sides by 220

Find the compound Interest for Rs.18,800 ,calculated for 2 years at 13% rate of Interest compounded annually

Vinvika [58]

For compound interest, the formula is given below:

Amount = $P(1+\frac{r}{100} )^{n}$

Here, P = 18,800

n = 2

r = 13/100

So, Amount = $18,800(1+\frac{13}{100} )^{2}$

$18,800(1.13)^{2}$

= 18,800 × 1.2769

= 24005.72

Compound Interest = Amount - Principal

Compound Interest = 24005.72 - 18800

= 5205.72

Hence, the compound interest for Rs.18,800, calculated for 2 years at 13% rate of interest compounded annually is Rs.5205.72.
