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 1 to 5 and that of Matrix (II) are numbered from 6 to 10. A letter from these matrices can be represented first by its row and next by its column, e.g. A can be represented by 11, 23, etc. and G can be represented by 67, 78, etc. Similarly, you have to identify the set for the word given below. BEE Matrix I
Matrix II

Question : If $\cos\theta - \sin\theta =0$, then $(\sin^8\theta+\cos^8\theta)$ is:
Option 1: $\frac{1}{8}$
Option 2: $ \frac{1}{4}$
Option 3: $\frac{1}{6}$
Option 4: $\frac{1}{2}$
Correct Answer: $\frac{1}{8}$
Solution : Given: $\cos\theta - \sin\theta =0$ ⇒ $\sin\theta = \cos\theta$ $\sin\theta$'s value is only equal with $\cos\theta$ when $\theta = 45°$ ⇒ $\sin\theta = \cos\theta = \frac{1}{\sqrt2}$ $(\sin^8\theta+\cos^8\theta)$ = $(\sin^845°+\cos^845°)$ = $(\frac{1}{\sqrt2})^8+ (\frac{1}{\sqrt2})^8$ = $\frac{1}{16}+\frac{1}{16}$ = $\frac{2}{16}$ = $\frac{1}{8}$ Hence, the correct answer is $\frac{1}{8}$.
Question : Directions: In a certain code language BLADE is written as CKBCF, and CHALK is written as DGBKL. How will DIGITAL be written in that language?
Option 1: FHGHVZN
Option 2: EHHHUZM
Option 3: FGGHVYN
Option 4: EGHGWYM
Correct Answer: EHHHUZM
Solution : Given: BLADE is written as CKBCF, and CHALK is written as DGBKL.
Add and subtract 1 alternatively to the place value of the letters of the word BLADE to find the required code – B + 1= C; L – 1 = K; A +
Question : What is the effective resistance (in Ω) of two resistors 20 Ω and 30 Ω connected in parallel?
Option 1: 50
Option 2: 12
Option 3: 24
Option 4: 25
Correct Answer: 12
Solution : The correct answer is 12.
The term "resistance" refers to the degree to which an electric network impedes the flow of electric current. In circuit analysis, this is known as effective resistance. To calculate the effective resistance between two resistors R1 and R2
Question : Directions: Select the letter cluster from among the given options that can replace the question mark (?) in the following series. JOQW, LQSY, ?, PUWC
