If the letters of the word CRICKET are arranged in all possible ways and these words are written out as in the dictionary, then the rank of the word CRICKET is
Detailed Solution for Gate Mock Test Civil Engineering (CE)- 7 - Question 5

Complete step-by-step answer:
We know that the alphabetical order of the letters of the given word CRICKET is C,C,E,I,K,R,T

⇒⇒The number of words beginning with CC will be 5! This is because CC will be one letter and is fixed at first and second place. We can arrange now 5 letters so the arrangement of 5 letters is 5! = 120.


⇒⇒The number of words beginning with CE will be 5! This is because CE will be one letter and is fixed at first and second place. We can arrange now 5 letters so the arrangement of 5 letters is 5! = 120.


⇒⇒The number of words beginning with CI will be 5! This is because CI will be one letter and is fixed at first and second place. We can arrange now 5 letters so the arrangement of 5 letters is 5! = 120.

⇒⇒The number of words beginning with CK will be 5! This is because CK will be one letter and is fixed at first and second place. We can arrange now 5 letters so the arrangement of 5 letters is 5! = 120.

⇒⇒The number of words beginning with CRC will be 4! This is because CRC will be one letter and is fixed at first, second and third place. We can arrange now 4 letters so the arrangement of 4 letters is 4! = 24.

⇒⇒The number of words beginning with CRE will be 4! This is because CRE will be one letter and is fixed at first, second and third place. We can arrange now 4 letters so the arrangement of 4 letters is 4! = 24.

⇒⇒The number of words beginning with CRICE will be 2! This is because CRICE will be one letter and is fixed at first, second, third, fourth and fifth place. We can arrange now 2 letters so the arrangement of 2 letters is
2!= 2.
Then we can say that the next word is CRICKET
Rank is 120+120+120+120+24+24+2+1=531
 So, the correct option is C.

Statement: Either P marries Q or X marries Y.

Among the options below, the logical NEGATION of the above statement is:
Detailed Solution for Gate Mock Test Civil Engineering (CE)- 7 - Question 6
Given statement: Either P marries Q or X marries Y. Negation is the grammatical operation whereby a proposition is replaced by one that states the opposite. In English language, sentences may be negated with the adverbs 'not' and 'never', the determiner 'no', and the indefinite pronouns 'no one', 'nobody', 'neither' and 'none' as well as other negative words.

Thus, the logical negation of the above statement is 'Neither P marries Q nor X marries Y.'

Sum of internal angle formed at pentagon = (5 - 2) x 180= 3 x 180

⇒ Each internal angle = (3 x 180)/5 = 108o

In △PA1A2

∠θ = ?; ∠x = 180 - 108 = 72; ∠y = 180 - 108 = 72

∴ ∠x + ∠y + θ = 180

⇒ θ = 180 - 72 - 72 = 36o

Consider the following unit steps commonly adopted in Solid Waste Management (SWM) of Municipal Solid Waste (MSW);

Collection (C), Transportation (TR), Disposal (D), and storage of MSW (SR). The order of these unit processes (first to last) in a conventional SWM system is:
Detailed Solution for Gate Mock Test Civil Engineering (CE)- 7 - Question 14
The order adopted is 1. Storage of Waste (SR), 2. Collection of waste (C), 3. Transportation of waste (TR), and 4. Disposal of waste (D)

Storage of waste at the source is the first essential step of SWM. The collection of waste is the second essential step of SWM activity. In the collection system, it is necessary to ensure that waste stored at the source is collected and is not disposed off on the streets, drains, water bodies, etc. The collection step has to coordinate well with the first step i.e. Storage of waste at the source. Then, In the third step (Transportation) - all the waste collected through the collection system, from the households, shops, and establishments has to be taken to the processing or disposal site. All the waste collected from the sources of waste generation is temporarily stored at a commonplace called "Waste storage deposits" and then at last it is transported in bulk to the processing/disposal sites.

If x = a cos θ, y = b sin θ, then d2y/dx2 at θ = π/2 is
Detailed Solution for Gate Mock Test Civil Engineering (CE)- 7 - Question 17
y = b sin θ , x = a cos θ

y' = b cosθ , x' = -a sinθ

dy/dx = y'/x' = b cosθ /(-a sin θ)
