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 =

Option 3: 105
Option 4: 115
Correct Answer: 95
Solution : Given: The average of 3 numbers is 135. The largest number is 195. The difference between the other two is 20. Let x be the smallest number. So, (x + 20) would be the second number. According to the question, 195 + x + x
Question : The next number of the sequences 3, 7, 15, 31, 63, ? is:

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
Option 4: Rs. 8000
Correct Answer: Rs. 8000
Solution : Rate, $R = 5$% Term, $n = 2$ years Let the principal be Rs. $P$. CI – SI = Rs. 20 Difference between CI and SI in 2 years = $\frac{PR^2}{10000}$ So, 20 = $\frac{P×5^2}{10000}$ ⇒ $P$ = Rs. 8000 Hence, the correct answer
