Question

Mehak lent Rs 8000 to Riya 12 and half% per annum compound interest find the amount payable by Riya to Mehak after 2 years​

Answer 1

Answer:

10125

Step-by-step explanation:

equivalent rate of interest for 2 yrs

= r + r + (r×r/100)

= 25/2 + 25/2 + 25/2*25/2/100

= 26.5625%

compound interest

= 26.5625% of 8000 = Rs 2125

A = 8000 + 2125 = 10125

2nd

C.I = 8000 [ (1+ 25/200)^2 - 1 ]

= 8000 × 0.265625 = 2125

amount = 8000 + 2125 = 10125

Answer 2

Answer:

Riya will pay 10,125 Rs to Mehak after 2 years.

Step-by-step explanation:

Given that-

Principal amount (P) = 8,000 Rs

Rate (r) = 12.5%

Time (n) = 2 years

Addition amount (A) =?

We know that-

$A = P[1+\dfrac{r}{100}]^{n}$

$A = 8000[1+\dfrac{12.5}{100}]^{2}$

$A = 8000[1+\dfrac{1}{8}]^{2}$

$A = 8000[\dfrac{9}{8}]^{2}$

$A = \dfrac{8000 \times9 \times9}{8 \times8}$

$A = \dfrac{648000}{64}$

A = 10,125 Rs

Hence, Riya will pay 10,125 Rs to Mehak after 2 years.
