✼GIVEN✼

✼PRINCIPAL=125000

✼RATE=8/4=2%(quarterly)

✼TIME=9/12*4=3 or n=3(quarterly)

✼Find=CP AND AMOUNT

✼ACCORDING TO THE QUESTION✼

$⇒a =p (1 + \frac{r}{100} ) {}^{n} \\ \\ ⇒a = 125000(1 + \frac{2}{100} ) {}^{3} \\ \\ ⇒a = 125000( \frac{102}{100} ) {}^{3} \\ \\ ⇒a = 125000 \times \frac{102}{100} \times \frac{102}{100} \times \frac{102}{100} \\ \\ ⇒a = \frac{125 \times 102 \times 102 \times 102}{10 \times 100} \\ \\⇒ a = 132651$

❃AMOUNT=132651

❃PRINCIPAL=125000
