★GIVEN

★PRINCIPAL=50,000

★TIME=2 years

★CP=6180

★AMOUNT=56180

★FIND:-RATE OF INTEREST

★According to the formula of cp★

$⇒amount = p(1 + \frac{r}{100} ) {}^{n} \\ \\ ⇒56180 = 50000(1 + \frac{r}{100} ) {}^{2} \\ \\⇒ \frac{56180}{50000} = (\frac{100 + r}{100} ) {}^{2} \\ \\ ⇒ \frac{2809}{2500} = ( \frac{100 + r}{100} ) {}^{2} \\ \\ ⇒( \frac{53}{50} ) {}^{2} = ( \frac{100 + r}{100} ) {}^{2} \\ \\ ⇒ \frac{53}{50} = \frac{100 + r}{100} \\ \\ ⇒5000 + 50r = 5300 \\ \\ ⇒50r = 5300 - 5000 \\ \\ ⇒50r = 300 \\ \\ ⇒r = 6\%$

Hence

the rate of interest is 6%
