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
