The question gives a cause, a major derailment of G.T. Express at Katpadi Junction in which seven bogies fell across the tracks, followed by three statements, and asks which of them can be effects of this cause. We need to check whether each statement follows directly and logically from the accident.
Identify the given information:
Examine Effect I:
Bogies lying across the tracks block the line at Katpadi. So, trains on the Katpadi–Chennai route are naturally delayed while the tracks are cleared. Hence, Effect I follows directly from the cause.
Examine Effect II:
Long queues at ticket counters in Bangalore can have many ordinary reasons, and nothing in the cause links the accident to ticket booking in Bangalore. So, Effect II does not follow directly.
Examine Effect III:
Running holiday special trains between Kolkata and Patna is a seasonal decision on a completely different route. It has no connection with the derailment. So, Effect III does not follow.
Correct Option: B) Only I is a possible effect. — The blocked tracks at Katpadi directly delay trains on the Katpadi–Chennai route, while II and III are unrelated to the accident. Hence, Option B is the correct answer.
A) Both I and II are possible effects.: This is incorrect because Effect II has no direct link to the derailment.
C) Both II and III are possible effects.: This is incorrect because neither II nor III follows from the accident, while I does.
D) Only II is a possible effect.: This is incorrect because Effect II is unrelated, and Effect I is the direct effect.
To solve this problem, we need to identify the vowels and consonants in the given word "PARKING". Then, we apply the given rule: change each vowel to the letter following it and each consonant to the letter following it in the English alphabetical order. Finally, we determine the third letter from the left in the newly formed word.
Combining the transformed letters, we get: Q B S L J O H
In the new group "QBSLJOH", the letters are:
The third letter from the left is 'S'.
Correct Option: B) S
To find the selling price after successive discounts, we need to apply each discount sequentially to the marked price. First, calculate the price after the first discount, and then apply the second discount to this new price.
The value of x is ₹345.
D) 345 is the correct selling price after applying successive discounts of 25% and 8% on the marked price of ₹500.
The question asks to identify which statements correctly describe the law of conservation of energy. We need to recall the fundamental principles of this law.
A) Both Statements I and II. Both statements are essential components of the law of conservation of energy. Statement II defines the conservation aspect, while Statement I describes the transformation aspect, both of which are central to the law.
The problem requires us to substitute the given symbols with their corresponding mathematical operations and then evaluate the expression following the order of operations (BODMAS/PEMDAS).
The original equation is: 61 D 39 C 14 C (62 A 2) B 4 = ?
Substituting the operations, we get:
\[ 61 - 39 + 14 + (62 \div 2) \times 4 = ? \]First, solve the operation inside the parentheses.
\[ 62 \div 2 = 31 \]Next, perform the multiplication.
\[ 31 \times 4 = 124 \]Now, perform addition and subtraction in the order they appear from left to right.
So, the value of the expression is \(160\).
C) 160 is the correct answer, as derived from the step-by-step calculation.
This is a syllogism problem that can be solved using Venn diagrams or by analyzing the logical relationships between the statements. We need to determine which conclusions logically follow from the given statements, treating the statements as absolutely true.
B) Only conclusion (I) follows
The question asks to identify the organelle that is exclusively found in plant cells. To answer this, we need to recall the distinguishing features of plant and animal cells and the organelles present in each.
Correct Option: B) Chloroplast is the organelle found exclusively in plant cells, where it performs photosynthesis.
Six people A, B, C, D, E and F sit around a circular table facing the centre, and the clues fix their relative positions. We need to apply the direction rule, place each person seat by seat and then read the position of C with respect to D.
Identify the given information:
Recall the direction rule:
When people sit around a table facing the centre, moving to a person's left means moving clockwise, and moving to a person's right means moving anticlockwise.
Place D, E and F:
Number the seats 1 to 6 clockwise and put D in seat 1. E is to the immediate right of D, so E is in seat 6. F is second to the right of D, so F is in seat 5.
Place A, B and C:
A is a neighbour of D; seat 6 is taken by E, so A is in seat 2. A is also a neighbour of B, so B is in seat 3. The remaining seat 4 goes to C.
Final arrangement (clockwise from seat 1): D, A, B, C, F, E.
Find the position of C with respect to D:
Moving clockwise (to D's left) from D in seat 1, we pass A and B and reach C in seat 4. So, C is third to the left of D.
Correct Option: D) Third to the left — With the arrangement D, A, B, C, F, E clockwise, C is three seats clockwise from D. Hence, Option D is the correct answer.
A) Immediate left: This is incorrect because the person to the immediate left of D is A.
B) Second to the left: This is incorrect because the person second to the left of D is B.
C) Second to the right: This is incorrect because the person second to the right of D is F.
To solve this problem, we need to apply the given rules to each letter in the word "BLEACH". The rules are: change each consonant to the letter immediately preceding it and each vowel to the letter immediately succeeding it in the English alphabetical order. After transforming all letters, we will identify which letter, if any, is repeated twice in the new group.
Combining the transformed letters in order, we get: A, K, F, B, B, G.
In the new group (A, K, F, B, B, G), the letter B appears twice.
Correct Option: D) B
The letter 'B' is repeated twice in the new group of letters (A, K, F, B, B, G).
To find the constant speed required, we use the fundamental formula relating speed, distance, and time. The problem provides the total distance to be covered and the total time available. We need to calculate the speed.
The relationship between speed, distance, and time is given by:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]Substitute \(D = 600 \text{ km}\) and \(T = 10 \text{ hrs}\) into the formula:
\[ \text{Speed} = \frac{600 \text{ km}}{10 \text{ hrs}} \]Perform the division:
\[ \text{Speed} = 60 \text{ km/h} \]Therefore, a constant speed of 60 km/h should be maintained.
Correct Option: A) 60 km/h
