     • Machine Learning: They teach computers to learn from data.

3. The Connection:

   • Data science and statistics are best friends:
     • They work together to solve real-world puzzles.
     • Statistics provides the tools, and data science uses them.
     • Imagine a detective (data scientist) using a magnifying glass (statistics) to crack the case (solve problems).

 A train running between two stations A and B arrives at its destination 15minutes late, when its speed is 45 km/hr. and 36 minutes late when its speed is 36 km/hr. find the distance between the stations A and B?

ANS:

Let ‘x’ km be the distance between the station A and B.

Speed of the train = 45 km/hr

Time taken =x/45 hours

Since the train is late by 15 minutes =1/4

Actual time =(x/45 -1/4)hr-------(1)

Time taken when the speed is 36 km/hr=x/36 hrs

Now, since the train is late by 36 min i.e.,36/60=3/5

actual time= (x/36-3/5)hrs ---------(2)

 Equating (1) and (2), we get x/45 -1/4 =x/36 -3/5 

∴ x/45 -1/4 =x/36 -3/5 

x=63km                       

 In a party of 80 people each person handshakes with the other. Find the total number of handshakes?

A)3160  B)3280 C)3260  D)2296

Answer:A)3160 

To calculate the number of handshakes, we can use the formula combination =nC2= n(n-1)/2, where n is the number of people. In this case, n = 80.

So, the number of handshakes would be 80(80-1)/2 = 3,160 handshakes.

 A sum of Rs.2000 is to be divided among three people so A,B and C.'A'receives thrice as much as 'B' and 'B' receives one fourth that of 'C'.Then A's share is?

A)Rs1000  B)Rs750 C)Rs250 D)Rs500

Ans:B)Rs750

Given:

Total sum to be divided: Rs. 2000

Three people: A, B, and C

A receives three times as much as B

B receives one fourth of C

Let's denote the amounts received by A, B, and C as follows:

Let B's share be x.

Then, A's share is 3x (three times as much as B).

And, C's share is 4x (since B receives one fourth of C).

Step 1: Setting up the Equations:

The total sum is divided among A, B, and C: A + B + C = 2000

Step 2: Expressing A, B, and C's Shares:

A = 3x

B = x

C = 4x

Step 3: Substituting into the Total Sum Equation:

3x + x + 4x = 2000

8x = 2000

x = 250

Step 4: Calculating A's Share:

A's share = 3x = 3 * 250 = Rs. 750

Therefore, A's share is Rs. 750 (Option B).

 40 men can do certain work in 25 days. After 10 days 25 men left. Find the number of days in which the remaining work is completed?

A)20 days      B)40 days C)15 days D)25 days

Ans:B)40 days

 Given:

40 men can complete a certain work in 25 days.

After 10 days, 25 men left.

Let's break down the problem into steps:

Step 1: Calculate the Total Work:

Let the total work be represented by ( W ).

40 men can complete the work in 25 days, so the total work is completed in ( 40 \times 25 = 1000 ) man-days.

Step 2: Work Done in 10 Days:

In 10 days, 40 men complete ( 40 \times 10 = 400 ) man-days of work.

Step 3: Work Remaining:

After 10 days, 25 men left, so the remaining men working are 40 - 25 = 15 men.

Work remaining after 10 days = Total work - Work done in 10 days = 1000 - 400 = 600 man-days.

Step 4: Calculate the Number of Days to Complete the Remaining Work:

The remaining work of 600 man-days will be completed by 15 men.

Number of days to complete the remaining work = Remaining work / (Men working * Days) = 600 / (15 * x), where x is the number of days.

Step 5: Solve for x:

( 600 = 15x )

( x = 600 / 15 = 40 )

Therefore, the number of days in which the remaining work is completed is 40 days (Option B).
