Question

COMPOUND INTEREST ON CERTAIN SUM OF MONEY FOR 3 YEARS AT 5 PERCENT PER ANNUM IS ₹5250.WHAT WILL BE THE COMPOUND INTEREST ON THAT SAME RATE FOR THE SAME TIME.

Answer 1

i feel u r doing some mistake in writing the question

ATQ, SI=PRT/100
$\frac{p \times 3 \times 5}{100} = 5250$
p=35000
$a = p \times {1 + \frac{r}{100} } {t}^{2}$
a=
$35000 \times \frac{105}{100} \times \frac{105}{100} \times \frac{105}{100 }$
$a = 40516.875$
$ci = a - p$

ci=40516.875-35000=Rs.5516.875
