Answer» Answer: Amount = Rs. 11664 Step-by-step explanation: GIVEN: PRINCIPAL amount (P) = Rs. 10000 Rate of INTEREST (r) = 8% Time (n) = 2 years To Find: Amount (A) Formula used: $\implies{\sf{Amount\;(A)=P\Bigg(1+\dfrac{r}{100}\Bigg)^{n}}}$ Put the values in the formula, $\implies{\sf{Amount\;(A)=P\Bigg(1+\dfrac{r}{100}\Bigg)^{n}}}$ $\implies{\sf{Amount\;(A)=10000\Bigg(1+\dfrac{8}{100}\Bigg)^{2}}}$ $\implies{\sf{Amount\;(A)=10000\Bigg(\dfrac{100+8}{100}\Bigg)^{2}}}$ $\implies{\sf{Amount\;(A)=10000\Bigg(\dfrac{108}{100}\Bigg)^{2}}}$ $\implies{\sf{Amount\;(A)=10000\Big(1.08 \Big)^{2}}}$ $\implies{\sf{Amount\;(A)=10000\times 1.08\times 1.08}}$ $\implies{\boxed{\sf{Amount\;(A)=Rs.\;11664}}}$

What is the amount for Rs. 10000 by compound interest at 8% rate for 2 years? 1️⃣ ₹ 50002️⃣ ₹ 116643️⃣ ₹ 156644️⃣ ₹ 10664

Answer» Answer:

Amount = Rs. 11664

Step-by-step explanation:

GIVEN:

PRINCIPAL amount (P) = Rs. 10000
Rate of INTEREST (r) = 8%
Time (n) = 2 years

To Find:

Amount (A)

Formula used:

$\implies{\sf{Amount\;(A)=P\Bigg(1+\dfrac{r}{100}\Bigg)^{n}}}$

Put the values in the formula,

$\implies{\sf{Amount\;(A)=P\Bigg(1+\dfrac{r}{100}\Bigg)^{n}}}$

$\implies{\sf{Amount\;(A)=10000\Bigg(1+\dfrac{8}{100}\Bigg)^{2}}}$

$\implies{\sf{Amount\;(A)=10000\Bigg(\dfrac{100+8}{100}\Bigg)^{2}}}$

$\implies{\sf{Amount\;(A)=10000\Bigg(\dfrac{108}{100}\Bigg)^{2}}}$

$\implies{\sf{Amount\;(A)=10000\Big(1.08 \Big)^{2}}}$

$\implies{\sf{Amount\;(A)=10000\times 1.08\times 1.08}}$

$\implies{\boxed{\sf{Amount\;(A)=Rs.\;11664}}}$

Answer» ong>Answer: PRINCIPAL for the first year = Rs.8000, Rate = 5% per ANNUM, T = 1 year INTEREST for the first year = = 100 P×R×T =Rs.[ 100 8000×5×1 ]=Rs.400 ∴ Amount at the end of the first year = Rs. (8000 + 400) = Rs. 8400 Now principal for the SECOND year = Rs.8400 Interest for the second year = 100 P×R×T =Rs.[ 100 8400×5×1 ]=Rs.420 ∴ Amount at the end of the second year = Rs. (8400 + 420) =Rs.8820 Interest for the third year = 100 P×R×T =Rs. 100 8820×5×1 =Rs.441 ∴ Amount at the end of the third year = Rs.(8820 + 441) = Rs. 9261 Now we KNOW that total C.I. = Amount - Principal = Rs. (9261 - 8000) = Rs. 1261 we can also find the C.I. as follows Total C.I. = Interest for the first year + Interest for the second year + Interest for third year = Rs.

Find the simple interest on rs 8000for three years at the rate of 4%

Answer»

ong>Answer: PRINCIPAL for the first year = Rs.8000, Rate = 5% per ANNUM, T = 1 year

INTEREST for the first year = =

100

P×R×T

=Rs.[

100

8000×5×1

]=Rs.400

∴ Amount at the end of the first year = Rs. (8000 + 400) = Rs. 8400

Now principal for the SECOND year = Rs.8400

Interest for the second year =

100

P×R×T

=Rs.[

100

8400×5×1

]=Rs.420

∴ Amount at the end of the second year = Rs. (8400 + 420) =Rs.8820

Interest for the third year =

100

P×R×T

=Rs.

100

8820×5×1

=Rs.441

∴ Amount at the end of the third year = Rs.(8820 + 441) = Rs. 9261

Now we KNOW that total C.I. = Amount - Principal = Rs. (9261 - 8000) = Rs. 1261

we can also find the C.I. as follows

Total C.I. = Interest for the first year + Interest for the second year + Interest for third year = Rs. (400 + 420 + 441) = Rs.1261

Answer» ong>Step-by-step explanation: Solution: (a) m∠A = 80°, m∠B = 60° m∠A + m∠B = 80° + 60° = 140° < 180° So, ΔABC can be possible to construct. (b) PQ = 5 cm, QR = 3 cm, PR = 8.8 cm PQ + QR = 5 cm + 3 cm = 8 cm < 8.8 cm or PQ + QR < PR So, the ΔPQR can not be constructed.

State whether the triangle is possible to construct if (a) In ΔABC, m∠A = 80°, m∠B = 60°, AB = 5.5 cm (b) In ΔPQR, PQ = 5 cm, QR = 3 cm, PR = 8.8 cm with diagram

Answer»

ong>Step-by-step explanation:

Solution:

(a) m∠A = 80°, m∠B = 60°

m∠A + m∠B = 80° + 60° = 140° < 180°

So, ΔABC can be possible to construct.

(b) PQ = 5 cm, QR = 3 cm, PR = 8.8 cm

PQ + QR = 5 cm + 3 cm = 8 cm < 8.8 cm

or PQ + QR < PR

So, the ΔPQR can not be constructed.
