Question 1: Permutation with Repeated Letters

Question:
How many different 8-letter words can be formed from the word SYLLABLES?

Solution:
First, analyze the frequency of the letters in "SYLLABLES":

• S = 2
• Y = 1
• L = 2
• A = 1
• B = 1
• E = 1

To calculate the total number of unique arrangements with repeated letters: Total permutations=8!2!×2!\text{Total permutations} = \frac{8!}{2! \times 2!}Total permutations=2!×2!8!​

This accounts for the repeated S and L.

Answer: Option C

Question 2: Indices Simplification

Question:
Evaluate 160.16×160.04×20.216^{0.16} \times 16^{0.04} \times 2^{0.2}160.16×160.04×20.2

Solution:

Step 1: Express 16 as a power of 2: 16=2416 = 2^416=24

So, (24)0.16=20.64,(24)0.04=20.16(2^4)^{0.16} = 2^{0.64}, \quad (2^4)^{0.04} = 2^{0.16}(24)0.16=20.64,(24)0.04=20.16

Now multiply: 20.64×20.16×20.2=20.64+0.16+0.2=21=22^{0.64} \times 2^{0.16} \times 2^{0.2} = 2^{0.64 + 0.16 + 0.2} = 2^1 = 220.64×20.16×20.2=20.64+0.16+0.2=21=2

Answer: Option A

Question 3: Binary Operations

Question:
Let * and ∘ be two binary operations defined as follows:

• a∗b=a2⋅ba * b = a^2 \cdot ba∗b=a2⋅b
• a∘b=2a+ba \circ b = 2a + ba∘b=2a+b

Find the value of: (−4∗2)∘(7∗−1)(-4 * 2) \circ (7 * -1)(−4∗2)∘(7∗−1)

Step 1: Solve −4∗2-4 * 2−4∗2

(−4)2⋅2=16⋅2=32(-4)^2 \cdot 2 = 16 \cdot 2 = 32(−4)2⋅2=16⋅2=32

Step 2: Solve 7∗−17 * -17∗−1

72⋅(−1)=49⋅−1=−497^2 \cdot (-1) = 49 \cdot -1 = -4972⋅(−1)=49⋅−1=−49

Step 3: Combine using ∘ operation:

32∘−49=2⋅32+(−49)=64−49=1532 \circ -49 = 2 \cdot 32 + (-49) = 64 - 49 = 1532∘−49=2⋅32+(−49)=64−49=15

Answer: 15
