• The question provides information about the monkey's apple consumption and the total number of mangoes eaten in 100 days.

• However, there is no direct information about the number of mangoes eaten on the first day.

• Without additional data or calculations, it is impossible to determine the exact number of mangoes eaten on the first day.

Minimum 31 socks need to be taken out to get 15 pairs of socks

• To get 15 pairs of socks, you need to have 30 socks of different colors

• After taking out 30 socks, the next sock you take out will complete the 15 pairs

• So, minimum 31 socks need to be taken out to get 15 pairs of socks

The question involves solving mathematical puzzles related to arranging objects and counting.

• For the calculator image, check for missing buttons, incorrect numbers, or distorted display.

• To arrange 10 pearls on a rectangle, place 2 pearls on each side and 2 pearls in each corner.

• To find a correct pair of socks, you need to take out 13 socks.

• To determine the number of men and horses, set up equations based on the number of heads and legs.

The number of apples eaten on the first day can be calculated by working backwards from the total number of apples eaten over 5 days.

• Calculate the total number of apples eaten over 5 days: 100 apples

• Subtract the apples eaten on the 2nd day (6 more than the 1st day), 3rd day (6 more than the 2nd day), and so on until the 5th day to find the apples eaten on the 1st day

• Example: 1st day = x, 2nd day = x + 6, 3rd day = x + 12, 4th day = x + 18, 5th day = x + 24. Total = 100 apples

The weight of the pen is 4 kg.

• To find the weight of the pen, we can set up the equation: pen weight = 2 kg + 1/2 of its own weight

• Let x be the weight of the pen. The equation becomes: x = 2 + 1/2 * x

• Solving for x, we get x = 4 kg

When designing an online carrom game, the saved data when the game is paused and resumed should include player scores, positions of coins, game state, and timer status.

• Player scores should be saved to ensure continuity.

• Positions of coins on the board should be saved to resume the game accurately.

• Game state (such as whose turn it is) should be saved to maintain the flow.

• Timer status should be saved to resume the game with the correct time remaining.

To correct the labels on 3 boxes with jumbled fruit labels, the least number of steps required is 2.

• Pick a fruit from the box labeled 'apples + oranges', since it must contain both fruits.

• Then pick a fruit from the box labeled 'oranges', as it cannot contain apples.

To calculate 15 mins using 11 mins and 7 mins hourglasses, start both hourglasses together. When the 7 mins hourglass runs out, flip it. When the 11 mins hourglass runs out, flip the 7 mins hourglass. When the 7 mins hourglass runs out again, 15 mins have passed.

• Start both hourglasses together

• When the 7 mins hourglass runs out, flip it

• When the 11 mins hourglass runs out, flip the 7 mins hourglass

• When the 7 mins hourglass runs out again, 15 mins have passed

HTTP is the protocol used for communication over web pages.

• HTTP stands for Hypertext Transfer Protocol

• It is the foundation of data communication on the World Wide Web

• HTTP uses a client-server model where the web browser acts as the client and sends requests to the web server

• The web server responds with the requested data in the form of HTML, images, videos, etc.

Create a 3 digit password based on given condition.

• The condition for the password is not provided.

• Without the condition, it is impossible to create a password.

• The password should be strong and not easily guessable.

Fill 4L using 5L and 3L jugs with minimum water wastage

• Fill the 3L jug and pour it into the 5L jug, leaving 1L in the 3L jug

• Empty the 5L jug, then pour the 1L from the 3L jug into the 5L jug

• Fill the 3L jug again and pour it into the 5L jug, now you have 4L in the 5L jug

A function that returns the addition and subtraction of two numbers.

• Create a function that takes two numbers as input parameters.

• Inside the function, calculate the sum of the two numbers and store it in a variable.

• Calculate the difference of the two numbers and store it in another variable.

• Return an array of strings containing the sum and difference.

Iterate through array to find 2nd largest element

• Iterate through array and keep track of largest and second largest elements

• Handle edge cases like empty array or array with less than 2 elements

• Example: ['3', '5', '2', '7', '1'] should return '5'

Print leaf nodes of binary tree

• Traverse the tree recursively

• If node is null, return

• If node is leaf node, print it

• Else, recursively traverse left and right subtrees

Node.js is a runtime environment for executing JavaScript code outside of a web browser. Promises are objects representing the eventual completion or failure of an asynchronous operation. Closures are functions that have access to their own scope, as well as the scope in which they were defined.

• Node.js is a runtime environment that allows you to run JavaScript on the server-side.

• Promises are used in asynchronous programming to handle the results of asynchronous operations.

Indexing in DBMS is a technique to improve the performance of queries by allowing faster retrieval of data.

• Indexing creates a data structure that allows for quick lookups of data based on specific columns.

• It helps in reducing the time taken to retrieve data from a database table.

• Examples of indexing methods include B-tree, Hash indexes, and Bitmap indexes.

JS in Java refers to JavaScript, a scripting language commonly used for web development.

• JavaScript is a high-level, interpreted programming language.

• It is commonly used for client-side web development.

• JS can be embedded in HTML pages to add interactivity.

• It is not the same as Java, which is a separate programming language.
