According to a coding scheme the sentence
Peacock is designated as the national bird of India is coded as 5688999 35 1135556678 56 458 13666689 1334 79 13366 This coding scheme has the following rules:
1. The scheme is case-insensitive (does not distinguish between upper case and lower case letters).
2. Each letter has a unique code which is a single digit from among 1,2,3, …, 9.
3. The digit 9 codes two letters, and every other digit codes three letters.
4. The code for a word is constructed by arranging the digits corresponding to its letters in a non-decreasing sequence.
Answer these questions on the basis of this information.

The Correct Option is A
Solution and Explanation
The correct answer is (A):
Given sentence:
"peacock is designated as the national bird of India"
is coded as:5688999 35 1135556678 56 458 13666689 1334 79 13366
Letter-to-digit analysis from known words:
- o and c → 9 (from peacock, of)
- f → 7 (from of)
- i → 3 (confirmed from is, India, designated)
- s → 5 (from is)
- a → 6 (from as)
- n → 6 (from national)
- d → 1 (from India)
- e → 5 (from designated)
- t → 8 (from the)
- h → 4 (from the)
- g → 7 (from designated)
- p, k → 8 (from peacock)
- b, r → 3 or 4 (from bird)
Finding the code for L:
From the word national, which appears as 13666689, we analyze the last few characters:
- L is the last letter in “national”
- The last digit in the code is 1
So we deduce:
L is coded as 1

The Correct Option is D
Solution and Explanation
The correct answer is (D):
Given sentence:
"peacock is designated as the national bird of India"
is coded as:5688999 35 1135556678 56 458 13666689 1334 79 13366
Decoded letters from words:
- o and c → 9 (from peacock, of)
- f → 7 (from of)
- i → 3 (confirmed from is, India, designated)
- s → 5 (from is)
- a → 6 (from as, designated)
- n → 6 (from national)
- d → 1 (from India)
- e → 5 (from designated)
- t → 8 (from the, national)
- h → 4 (from the)
- g → 7 (from designated)
- l → 1 (from national)
- p and k → 8 (from peacock)
From the word "bird":
We know the letters are: b, i, r, d
- i = 3
- d = 1
- r = 4
Thus, the remaining code in the sequence 1334 must be for b, which leaves either 3 or 4.
Therefore, the code for B is either 3

The Correct Option is D
Solution and Explanation
The correct answer is (D):
The sentence:
"peacock is designated as the national bird of India"
is coded as: 5688999 35 1135556678 56 458 13666689 1334 79 13366
Letter-to-digit mappings:
- 9 →
oandc(from peacock and of) - 7 →
fandg(from of and designated) - 3 →
i(confirmed from is, India, and designated) - 5 →
sande(from is, designated) - 6 →
aandn(from as, national) - 1 →
dandl(from India, national) - 8 →
t,p, andk(from the, peacock) - 4 →
handr(from the, bird)
From the word bird, we get:
b→ 3r→ 4d→ 1i→ 3
So, the codes for:
B= 3R= 4D= 1I= 3G= 7H= 4L= 1E= 5T= 8O,C= 9
From the analysis, most letters can be clearly associated with unique digits, but only 2 digits remain unaccounted for from the 10 possible digits (0–9), suggesting that:
Answer: 2 letters still need to be assigned distinct unused digits.

The Correct Option is A
Solution and Explanation
The correct answer is (A):
Given the sentence:
“peacock is designated as the national bird of India”
is coded as: 5688999 35 1135556678 56 458 13666689 1334 79 13366
Code deductions from known mappings:
- 9 is used for
oandc(from peacock and of) - 7 is the code for
f(from of) - 3 is used for
i(from India, is, designated) - 5 is for
s(from is) - 6 is for
aandn(from as, national) - 1 is for
dandl(from India, national) - 8 is for
tandp,k(from the, peacock) - 4 is for
handr(from the, bird)
From “bird”, the letters b, i, r, d correspond to:
b= 3i= 3r= 4d= 1
Now focus on what is not coded with same digit:
S = 5UandVappear nowhere in the coded sentence- So we cannot reuse codes for
S, U, Vfrom known data
Therefore, S, U, V cannot be coded with the same digit.
Final Answer: S, U, V

Students who are guided by the same guide must be scheduled in consecutive slots.
The following additional facts are also known.
1. Seminars by students from Economics are scheduled in each of the four slots.
2. A’s is the only seminar that is scheduled at 10:00 am. A is guided by R.
3. F is an Anthropology student whose seminar is scheduled at 10:30 am.
4. The seminar of a Sociology student is scheduled at 9:00 am.

The following figure shows the percentages of revenue and cost from the three departments for the years 2016, 2017 and 2018. The dotted lines depict percentage levels. So for example, in 2016, 50% of store's revenue came from its Electronics department while 40% of its costs were incurred in the Produce department.
In this setup, Profit is computed as (Revenue – Cost) and Percentage Profit as Profit/Cost × 100%.
It is known that
1. The percentage profit for the store in 2016 was 100%.
2. The store’s revenue doubled from 2016 to 2017, and its cost doubled from 2016 to 2018.
3. There was no profit from the Electronics department in 2017.
4. In 2018, the revenue from the Clothing department was the same as the cost incurred in the Produce department.
