The problem requires us to evaluate a given mathematical expression after interchanging certain operators. We need to follow the order of operations (BODMAS/PEMDAS) after applying the specified changes to the operators.
The value of the expression after the changes is \(95\).
A) 95 is the correct answer, as calculated by applying the operator changes and following the order of operations.
The question asks to identify the 26th Chief Election Commissioner of India appointed in February 2025. This requires knowledge of recent appointments to constitutional posts, which is a common topic in competitive exams.
Correct Option: D) Gyanesh Kumar. While the appointment of the 26th CEC is a future event as per the question's timeline (February 2025), based on the appointments made in March 2024, Gyanesh Kumar is a strong contender for the position, assuming seniority and the typical progression within the Election Commission. He was appointed as an Election Commissioner in March 2024. If he is the senior-most Election Commissioner when the 25th CEC retires in February 2025, he would be elevated to the 26th Chief Election Commissioner.
The problem asks us to find the simple interest earned over a given period when the principal amount, rate of interest, and time are known. We are given the rate of simple interest, the time period, and the final amount (Principal + Simple Interest). We can use the simple interest formula and the formula for the amount to find the principal and then the simple interest.
Simple Interest (\(SI\)) is calculated as:
\[ SI = \frac{P \times R \times T}{100} \]where \(P\) is the Principal.The Amount (\(A\)) is the sum of the Principal (\(P\)) and the Simple Interest (\(SI\)):
\[ A = P + SI \]Now that we have the Principal, we can find the Simple Interest using \(SI = A - P\):
\[ SI = 7500 - 6000 \]\[ SI = 1500 \]Alternatively, we can use the simple interest formula directly with the calculated principal:\[ SI = \frac{6000 \times 12.5 \times 2}{100} \]\[ SI = \frac{6000 \times 25}{100} \]\[ SI = 60 \times 25 \]\[ SI = 1500 \]A) 1,500 is the calculated simple interest for the given time period.
The question asks to identify a physiographic feature that lies parallel to the Shiwaliks and has a specific width (8-16 km). This requires knowledge of the physiographic divisions of the Northern Plains of India, particularly the features formed at the foot of the Himalayas.
A) Bhabar — The Bhabar belt is a narrow strip (8-16 km wide) that runs parallel to the Shiwalik foothills. It is composed of pebbles and boulders deposited by rivers descending from the mountains. Due to the porosity of this region, streams often disappear underground here.
The problem asks us to identify the lowest and highest numbers from a given set of three-digit numbers, then extract their first digits, and finally subtract the first digit of the lowest number from the first digit of the highest number.
The resultant value is 7.
Correct Option: B) 7
The problem asks us to find the letter clusters that replace '#' and '%' based on a given pattern and relationship. We need to analyze the relationship between the letter-cluster pair on the left side of '::' (i.e., # : EPV) and apply the same logic to the right side (RFS : %). This involves identifying the positional changes of letters in the alphabet.
The correct option is D because when # is DNU, the transformation to EPV is +1, +2, +1 for each letter. Applying the same +1, +2, +1 transformation to RFS yields SHT for %.
And for the second pair:
Thus, # = DNU and % = SHT.
The question provides two words, MICE and PEAR, along with their numerical codes, 6398 and 3215. We need to identify the code for the letter E by comparing the common letters and common digits in both coded words.
Identify the given words and their codes:
We need to determine the numerical code representing the letter E.
Compare the letters in both words:
The letters in MICE are M, I, C and E.
The letters in PEAR are P, E, A and R.
The only common letter in both words is E.
Compare the digits in both codes:
The digits in 6398 are 6, 3, 9 and 8.
The digits in 3215 are 3, 2, 1 and 5.
The only common digit in both codes is 3.
Identify the code for E:
Since E is the only common letter and 3 is the only common digit in both coded words, the letter E corresponds to the digit 3.
\[ E=3 \]Therefore, the code for E is 3.
Correct Option: C) 3 — The letter E appears in both MICE and PEAR. Similarly, the digit 3 appears in both numerical codes, 6398 and 3215. Since E is the only common letter and 3 is the only common digit, E is coded as 3. Hence, Option C is the correct answer.
A) 2: This is incorrect because the digit 2 appears only in the code 3215, whereas E is present in both words.
B) 5: This is incorrect because the digit 5 appears only in the code 3215, whereas E appears in both words.
D) 8: This is incorrect because the digit 8 appears only in the code 6398, whereas the code for E must be common to both numerical codes.
The question asks to identify which two countries share the Thar Desert as a natural boundary. This requires knowledge of the geographical location of the Thar Desert and the countries it borders.
Correct Option: B) India and Pakistan. The Thar Desert is located on the border between India and Pakistan, serving as a natural geographical divide between the two nations, particularly in the states of Rajasthan (India) and Sindh (Pakistan).
The question asks about the system abolished by the Nineteenth Amendment Act of 1966. To answer this, we need to recall the key provisions and impacts of this specific constitutional amendment.
Therefore, the system abolished by the Nineteenth Amendment Act, 1966, was the Election Tribunals.
Correct Option: A) Election tribunals
The problem asks us to identify numbers in a given series that are immediately preceded by another number and immediately followed by a symbol. We need to scan the series from left to right and apply this condition to each element.
The given series is: 8 9 # 1 9 © 3 5 © € @ # £ @ * © 5 £ € 5 4 4
We are looking for a pattern: Number - Number - Symbol
Let's go through the series:
The numbers that satisfy the condition are:
There are 3 such numbers.
A) 3 is the correct answer as we found 3 numbers that fit the given criteria.
