Explanation:
Compound Interest
When the interest accumulated from time to time till now is calculated in the principal amount, then it is called compound interest.
Compound interest CI received on a certain sum of money of Rs P invested at the rate of r % per annum compounded quarterly for n years is as follows:
\boxed{\:\sf{CI = P {\bigg[1 + \dfrac{R}{400} \bigg]}^{4n} - P\:}}
CI=P[1+
400
R
]
4n
−P
Where,
CI - Compund Interest
P - Principal Amount
R - Rate of Interest
n - Time Period.
As per the provided information in the given question, we have been given that,
Principal amount, P = Rs. 12000
Rate of interest, R = 8% per annum
Time period, n = 1 year
Compound interest, CI = ?
Solution:
By substituting the given values in the formula, we get the following results:
\implies CI = P{\bigg[1 + \dfrac{R}{400} \bigg]}^{4n} - P⟹CI=P[1+

\implies CI = 0.00192 \times 6765201 - 12000⟹CI=0.00192×6765201−12000
\implies CI = 12989.18 - 12000⟹CI=12989.18−12000
\implies CI = 12989.18 - 12000⟹CI=12989.18−12000
\implies \boxed{\textsf{\textbf{CI = 989.1859}}}⟹
CI = 989.1859
Therefore, the compound interest is Rs. 989.1859.
Answer:
Nobel Laureate, Wangari Maathai, has underscored the importance of good governance in the effective and sustainable management of the continent’s natural resources. Speaking in Tunis, Tunisia, on Tuesday, October 27, 2009, within the framework of the African Development Bank (AfDB) Group’s Eminent Speakers Program, Prof. Maathai noted that poverty and environmental degradation on the continent were results of poor governance. She warned of dire consequences for Africa if the continent failed to create and maintain good governance structures that enhance natural resource development and environmental protection.
“Species that have had their habitat destroyed eventually die off,” she said, noting that though “man is the only species that thinks and projects into the future, its activities are destroying the environment.”
She called on Africans to be critical of themselves as a means of making progress in the areas of natural resource management, sustainable development and poverty reduction. She blamed the continent’s perennial poverty on the mismanagement of the continent’s natural resources, adding that good governance was the missing piece in the continent’s development paradigm. She called for responsible and accountable leadership on the continent, underscoring that poverty could not be overcome across the continent if basic notions such as equity, justice and peace were not taken seriously.
