The problem involves finding an unknown number given its relationship with another number, their HCF (Highest Common Factor), and LCM (Least Common Multiple). We will use the fundamental relationship between HCF, LCM, and the product of two numbers: \(\text{Product of two numbers} = \text{HCF} \times \text{LCM}\). We are also given two conditions relating the HCF and LCM: one about their ratio and another about their sum.
C) 234 is the other number.
To find the unit digit of a product, we only need to consider the unit digits of the numbers being multiplied. If any of the numbers in a product has a unit digit of 0, or if a pair of numbers has unit digits that multiply to a number ending in 0 (e.g., 2 and 5), then the unit digit of the entire product will be 0.
C) 0 is the correct answer because the product includes 95 (unit digit 5) and an even number like 92 (unit digit 2), and \(5 \times 2 = 10\), which has a unit digit of 0. Therefore, the unit digit of the entire product will be 0.
The question asks about the provisions of the Rowlatt Act of 1919. To answer this, recall the key features and objectives of this controversial legislation enacted by the British government in India.
Therefore, the most accurate description of what the Rowlatt Act entailed is indefinite detention without trial and censorship of the press.
Correct Option: A) Indefinite detention without trial and censorship of the press
To find the least possible number of bottles required, we first need to determine the largest possible size of an individual bottle. Since each bottle must be completely filled with one type of liquid without mixing, the capacity of the bottle must be a common divisor of the volumes of all three liquids. To minimize the number of bottles, the capacity of each bottle should be the greatest common divisor (GCD) of the volumes of diesel, petrol, and oil. Once the GCD is found, we can calculate the number of bottles for each liquid and sum them up to get the total least number of bottles.
Correct Option: D) 278
The problem involves decoding a pattern in a given word transformation. We need to identify the rule applied to transform "SPIDER" into "RNHBDP" and then apply the same rule to "QUESTION" to find its coded form.
Original word: S P I D E R
Coded word: R N H B D P
The pattern observed is a subtraction of 1 from the first letter's position, 2 from the second, 1 from the third, 2 from the fourth, and so on. The pattern is \(-1, -2, -1, -2, -1, -2, \ldots\).
Original word: Q U E S T I O N
The coded word for QUESTION is PSDQSGNL.
D) PSDQSGNL is the correct coded word derived by applying the \(-1, -2, -1, -2, \ldots\) pattern to each letter of "QUESTION".
The question asks to identify which option is NOT a sub-field of Economic Geography. To answer this, we need to understand what Economic Geography entails and then evaluate each option against this understanding.
C) Demography — Demography is the scientific study of human populations, including their size, structure, distribution, and how these change over time due to birth, death, migration, and aging. While population characteristics are crucial for understanding economic activities, demography is generally considered a separate discipline, often under sociology or population studies, rather than a direct sub-field of Economic Geography. Economic geography often uses demographic data, but demography itself is not a sub-field of it.
The problem is based on a coding-decoding pattern. We need to identify the rule by which "LOVE" is coded as "NQXG" and then apply the same rule to decode "SWEET". This usually involves finding the positional shift of each letter in the alphabet.
The pattern observed is that each letter in the word is shifted forward by 2 positions in the English alphabet.
So, SWEET will be coded as UYGGV.
Correct Option: D) UYGGV
The question asks about the primary purpose of building stupas in Buddhism. To answer this, we need to recall the historical and religious significance of stupas.
C) They contained sacred relics
Stupas were primarily built to house the bodily relics of the Buddha and later, those of prominent Buddhist monks and saints. These relics were considered highly sacred, and the stupas served as memorials and objects of veneration for Buddhists. This practice dates back to the time immediately after the Buddha's Mahaparinirvana, when his relics were distributed and enshrined in various stupas.
The question asks to identify the plant tissue responsible for transporting water from the roots to other parts of the plant. This involves recalling the functions of various plant tissues, particularly the vascular tissues.
Correct Option: C) Xylem tissue is the primary vascular tissue responsible for the upward transport of water and minerals from the roots to the aerial parts of the plant.
The question asks about the origin of the Brahmo Samaj, a significant socio-religious reform movement in India. To answer this, one needs to recall the historical context and the geographical location associated with its founder and early activities.
Correct Option: B) The Brahmo Samaj was founded in Calcutta (now Kolkata), which is located in Bengal, by Raja Ram Mohan Roy in 1828. This makes Bengal its place of origin.
