Question : The amount of Rs. 10,000 after 2 years, compounded annually with the rate of interest being 10% per annum during the first year and 12% per annum during the second year, would be (in rupees):
Option 1: 11,320
Option 2: 12,000
Option 3: 12,320
Option 4: 12,500
Correct Answer: 12,320
Solution : Present value (P) = Rs. 10,000 Interest rate for 1st year, $r_1$ = 10% per annum Interest rate for 2nd year, $r_2$ = 12% per annum Time = 2 years Amount(A) = P × (1 + $\frac{r_1}{100}$) × (1 + $\frac{r_2}{100}$) = 10000 × (1

Question : $\frac{(1+\tan \theta+\sec \theta)(1+\cot \theta-\operatorname{cosec} \theta)}{(\sec \theta+\tan \theta)(1-\sin \theta)}$ is equal to:
Option 1: $2 \sec \theta$
Option 2: $2 \operatorname{cosec} \theta$
Option 3: $\operatorname{cosec} \theta$
Option 4: $\sec \theta$
Correct Answer: $2 \sec \theta$
Solution : $\frac{(1+\tan \theta+\sec \theta)(1+\cot \theta-\operatorname{cosec} \theta)}{(\sec \theta+\tan \theta)(1-\sin \theta)}$ $=\frac{(1+\frac{\sin \theta}{\cos \theta}+\frac{1}{\cos \theta})(1+\frac {\cos \theta}{\sin \theta}-\frac {1}{\sin \theta})}{(\frac{1}{\cos \theta}+\frac{\sin \theta}{\cos \theta})(1-\sin \theta)}$ $=\frac{(\frac{\cos \theta+\sin \theta+1}{\cos \theta})(\frac {\sin \theta+\cos \theta-1}{\sin \theta})}{(\frac{1+\sin \theta}{\cos \theta})(1-\sin \theta)}$ $=\frac{(\cos \theta+\sin \theta+1)(\sin \theta+\cos \theta-1)}{\sin \theta(1-\sin \theta)}$ $=\frac{(\cos \theta+\sin \theta)^2-1}{\sin \theta\cos^2
