Question : In the given figure, $ABC$ is an isosceles triangle with $\mathrm{BC}=8 \mathrm{~cm}$ and $\mathrm{AB}=\mathrm{AC}$ $=5 \mathrm{~cm}$. The value of $\tan \mathrm{C}-\cot \mathrm{B}$ is______.
Option 1: $-\frac{5}{12}$
Option 2: $-\frac{7}{12}$
Option 3: $\frac{7}{12}$
Option 4: $\frac{5}{12}$
Correct Answer: $-\frac{7}{12}$
Solution : Given, $ABC$ is an isosceles triangle with $\mathrm{BC}=8 \mathrm{~cm}$ and $\mathrm{AB}=\mathrm{AC}$ $=5 \mathrm{~cm}$ In $\Delta ABC$, $AD$ is the perpendicular bisector. $BD=DC=\frac{BC}2$ $⇒BD=DC = \frac{8}2 = 4$ In $\Delta ADC$, by Pythagoras Theorem, $AC^2 = DC^2 + AD^2$ $⇒5^2 = 4^2 + AD^2$ $⇒AD^2 =
Question : If the difference between the compound interest and simple interest on a certain sum at the rate of 5% per annum for 2 years is Rs. 20, then the sum is:
Option 1: Rs. 2000
Option 2: Rs. 4000
Option 3: Rs. 6000
