Short Trick.

Count total number of days (except given day of week which in this question is Tuesday).

10 + Yesterday + 11 + Tomorrow = 10 + 1 + 11 + 1 = 23 days

23 days = 2 odd days.

Thus, 2 days ahead of Tuesday will be Thursday

Hence answer is Thursday

Detailed Method:

From given information;

10 days before yesterday’s → Tuesday.

So, the present day = 10 days + yesterday + Today. (12 days)

12 days = 5 odd days.

So, Present day is 5 days ahead of Tuesday, which is Sunday.

Thus 11^th day will come after 10 days

So total days = 10 + 1 (tomorrow) = 11 days.

11 days = 4 odd days.

So, 4 days ahead of Sunday is Thursday.

Hence answer is Thursday.

According to the given information :

Additional Information

Here, we use the table given below-

The logic followed here is-

• All the letters are rearranged according to their position values in descending order.

So,

• ‘FIXED’ is coded as :-

• ‘MOUSE’ is coded as :-

Similarly,

• ‘GAMBIT’ is coded as:-

Here, ‘GAMBIT’ is written as  TMIGBA.

Hence, the correct answer is “TMIGBA”.

The bus usually leaves on time.→ this means the bus leaves on time but we can’t say about today because it is not mentioned.

The departure time is 10:00 hrs.→ this means the time of leaving of the bus is 10:00 hrs. but we can’t conclude that the bus leaves on time today because it is not mentioned.

Hence, the answer is insufficient data. 

The pattern followed here is:

Hence, ’73’ is the correct answer.

The correct answer is Michel Talagrand

In News

•  Michel Talagrand of the French National Center for Scientific Research (CNRS), Paris, France, has been awarded the Abel Prize for 2024.

Key Points

• Talagrand’s contributions lie in probability theory and stochastic processes, which are crucial in understanding random phenomena prevalent in various aspects of modern life.
• Professor Helge Holden, chair of the Abel Prize Committee, acknowledges Talagrand as an exceptional mathematician and problem solver, whose work has reshaped several areas of probability theory.
• His proof of the Parisi formula for free energy of spin glasses is particularly lauded.
• Talagrand was born in France in 1952 and earned his PhD in mathematics from the University of Paris VI in 1977.
• He has also spent time at Ohio State University in the US and is a member of the French Academy of Sciences.

• Specific Areas of Work Recognized:
• Suprema of Stochastic Processes: Talagrand’s work involves understanding the largest values to be expected from sequences of random values, such as the height of waves crashing on a beach.
• Concentration of Measures: Talagrand provided quantitative estimates for how different sources of randomness can compensate for each other, leading to more predictable results in certain processes.

In first dice and second dice:

Given:

Logic: If two dice have the same face value in the given image then their clockwise or anticlockwise wise number are known as opposite numbers in dice.

In first dice and second dice. The symbol ‘l’ is common.

The left letter will be opposite each other writing them clockwise starting from I.

Hence, the face opposite the H is “@”.

Hence, the correct answer is “@”

Explanation: Madhya Pradesh is known as the ‘Tiger State of India’ and has the highest number of national parks, including Kanha, Bandhavgarh, and Pench.

Explanation: Simlipal National Park in Odisha is a tiger reserve and part of the UNESCO Biosphere Reserves list.

Explanation: Kanha National Park in Madhya Pradesh inspired Rudyard Kipling’s The Jungle Book, and it is home to tigers and other wildlife.

The logic followed here is:

Logic: Sum of all the numbers = 100

38 + 56 + 6 = 100;

38 + 16 + 46 = 100;

Similarly,

55 + 43 + ? = 100

98 + ? = 100

? = 100 – 98 = 2

Hence, the answer is “2”.
