Question : The simplest value of $\sin^{2}x+2\tan^{2}x-2\sec^{2}x+\cos^{2}x$ is:
Option 1: 1
Option 2: 0
Option 3: –1
Option 4: 2
Correct Answer: –1
Solution : Given: $\sin^{2}x+2\tan^{2}x-2\sec^{2}x+\cos^{2}x$ We know that, $\sec^2x=\tan^2x+1$ and $\sin^2x+\cos^2x=1$ Putting the values, we get: = $\sin^{2}x+2\tan^{2}x-2(\tan^2x+1)+\cos^{2}x$ = $\sin^{2}x+\cos^{2}x+2\tan^{2}x-2\tan^2x-2$ = $1-2$ = $-1$ Hence, the correct answer is –1.
Question : Select the sentence that has a spelling error.

Question : Directions: A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. H can be represented by 00, 24, etc, and L can be represented by 56, 98, etc. Similarly, you have to identify the set for the word HALT.
Option 1: 31, 59, 68, 21
Option 2: 43, 86, 99, 40
