Question

Without using formula, find the compound interest and amount on 25,000 for 2 years at 12% per annum.

PLEASE ANSWER correctly and urgently.​

Answer 1

Answer:

$p = rs.25000 \\ n = 3years \: \\ r = 12\% \: p.a \: \\ amount \: = (1 + \frac{r}{100} )^{n} = \: rs.25000 \times (1 + \frac{12}{100})^{3} \\ = rs.25000 \times (\frac{112}{100} ) \\ = rs.25000 \times \frac{28}{25} \times \frac{28}{25} \times \frac{28}{25} \\ = rs.35123.20 \\ compound \: interest = rs. \: (35123.20 - 25000) \\ = rs. \: 10123.20$

Answer 2

Answer:

  P = Rs. 25000, n = 3 years, r = 12% p.a

∴ Amount =P(1+100r)n=Rs.25000×(1+10012)3

=Rs.25000×(100112)3=Rs.25000×2528×2528×2528=Rs.35123.20

∴ Compound interest =Rs.(35123.20−25000)=Rs.10123.20
