Q8: The principal, which will amount to Rs. 270.40 in 2 years at the rate of 4% per annum compound interest is?

Explanation

Let the principal be Rs. P.
According to the question,
$∴ 270.40 = P (1 + \frac{4}{1 0 0})^{2}$
$\Rightarrow 270.40 = P (1 + 0.04)^{2}$
$\Rightarrow P = \frac{2 7 0 . 4 0}{1 . 0 4 \times 1 . 0 4}$ = Rs. 250
Hence, the principal is Rs. 250.

Q9: The value of an article which was purchased 2 years ago, depreciates at 12 % per annum. If its present value is Rs .9680, the price at which it was purchased is?

Explanation

Given, $A =$ Rs. $9680, T = 2$ years, $R = 12 %$
$∵ A = P (1 - \frac{R}{1 0 0})$
$9680 = P (1 - \frac{1 2}{1 0 0})^{2}$
$9680 = P (\frac{8 8}{1 0 0})^{2}$
$P = 9680 \times \frac{2 5}{2 2} \times \frac{2 5}{2 2}$
$=$ Rs. $12, 500$

Explanation

Let the principal be Rs. P. According to the question,∴270.40=P(1+1004​)2 ⇒270.40=P(1+0.04)2⇒P=1.04×1.04270.40​ = Rs. 250Hence, the principal is Rs. 250.

Q9: The value of an article which was purchased 2 years ago, depreciates at 12 % per annum. If its present value is Rs .9680, the price at which it was purchased is?

Explanation

Given, A= Rs.9680,T=2 years,R=12%∵A=P(1−100R​)9680=P(1−10012​)29680=P(10088​)2P=9680×2225​×2225​= Rs. 12,500

Q10: Two numbers are respectively 20% and 50% more than a third number. The ratio of two numbers is?

Explanation

Let the principal be Rs. P.
According to the question,
$∴ 270.40 = P (1 + \frac{4}{1 0 0})^{2}$
$\Rightarrow 270.40 = P (1 + 0.04)^{2}$
$\Rightarrow P = \frac{2 7 0 . 4 0}{1 . 0 4 \times 1 . 0 4}$ = Rs. 250
Hence, the principal is Rs. 250.

Given, $A =$ Rs. $9680, T = 2$ years, $R = 12 %$
$∵ A = P (1 - \frac{R}{1 0 0})$
$9680 = P (1 - \frac{1 2}{1 0 0})^{2}$
$9680 = P (\frac{8 8}{1 0 0})^{2}$
$P = 9680 \times \frac{2 5}{2 2} \times \frac{2 5}{2 2}$
$=$ Rs. $12, 500$
