Inner Join only includes rows that have matching values in both tables

Left Join includes all rows from the left table, even if there are no matching rows in the right table

Example : Inner Join - SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.id

Example : Left Join - SELECT * FROM table1 LEFT JOIN table2 ON table1.id = table2.id

Inner joins, outer joins, and left join are types of SQL joins used to combine data from multiple tables.

Inner join returns only the matching records from both tables.

Outer join returns all records from both tables, including non-matching records.

Left join returns all records from the left table and the matching records from the right table.

Example : INNER JOIN customers ON orders.customer_id = customers.customer_id

Example : LEFT JOIN customers ON orders.customer_id = customers.customer_id

if you have knowledge of excel tell me difference between hlookup,vlookup and xlookup?

EXL Service MCQ :

1 .

A train moving at speed of 80 km/hr crosses a pole in 7 seconds. Find the length of the train.

150 m

165 m

170 m

175 m

Correct Answer : 175 m

Explanation : Length of the train is equal to the distance covered by train to cross the pole. So, we will find the distance travelled by train in 7 seconds by applying the following formula:
Distance= Speed x Time
Speed is given in Km/hr so we will convert it into m/s as answers are given in meters.
Speed=90* (5/18)= 25 m/s
Time = 7 seconds
Distance = 25 * 7= 175 meters

2 .

A clock is set at 4 am. It loses 16 minutes in 24 hours. What will be the correct time when the clock indicates 9 pm on the 4th day?

8 pm

10 pm

11 pm

12 pm

Correct Answer : 10 pm

Explanation : Time from 4 am on a day to 9 pm on the 4th day = 89 hours

As per the question, 23 hrs 44 minutes of this clock = 24 hours of the correct clock as this clock loses 16 minutes in 24 hours.

23 hrs 44 minutes = 356/15 hrs

Now, 356/15 Hrs of this clock = 24 hours of correct clock

89 hours of this clock = (24*15/356) * 89 = 90 hours of the correct clock, i.e. the correct clock gains one hour over the incorrect clock.

The correct time on the fourth day would be 10pm.

3 .

If Suresh borrows Rs. 36000 from Mahesh at the rate of interest 6% (S.I), at the end of four years how much interest Suresh has to pay along with the principal amount?

Rs. 12560

Rs. 12780

Rs. 12960

Rs. 13500

Correct Answer : Rs. 12960

Explanation : Principal amount = Rs. 36000
Rate of interest = 6
Number of years or time = 6 years
S.I Formula = (P*r*t)/100
Simple Interest = 36000*6*6/100 = 12960

4 .

A man tossed two dice. What is the probability that the total score is a prime number?

5/12

5/14

5/20

5/24

Correct Answer : 5/12

Explanation : n (S) = 6*6 = 36
And, the event that the sum is a prime number:
E = {(1, 1), (1, 2), (1, 4), (1, 6), (2, 1), (2, 3), (2, 5), (3, 2), (3, 4), (4, 1), (4, 3),
(5, 2), (5, 6), (6, 1), (6, 5)}
So, n (E) = 15
P(E)= n(E)/n(S) = 15/36 = 5/12

5 .

The first republic day of India was celebrated on January 26, 1950. What day of the week was it?

Friday

Thursday

Tuesday

Wednesday

Correct Answer : Thursday

Explanation : 1600 years are divisible by 400, so the year 1600 has 0 odd days.

=> 300 years have 1 odd day.

=> 49 years = (12 leap years + 37 years)

= (12*2, odd days + 37*1, odd days)

= 24 + 37 = 61 odd days

On dividing 61 by 7, we get remainder 5, so 49 years have 5 odd days.

=>From January 26, 1950, to January 26, 1950, we have 26 days.

26 days = 3 weeks + 5 odd days

So, total number of odd days = 1 + 5 + 5 = 11 days

=>11 days = 1 week + 4 odd days

4 Odd days represent Thursday, so it was Thursday on January 26, 1950.

6 .

What is the compound interest on Rs. 2500 for 2 years at rate of interest 4% per annum?

Rs. 170

Rs. 180

Rs. 190

Rs. 204

Correct Answer : Rs. 204

Explanation : Principal (P) = Rs. 2500
Rate of interest(r) = 4%
Time (t) = 2 years
Compound Interest = Amount - Principal
Amount (A) =P[(1+(r/100)]^t
=2500[1+(4/100)]²
=2500+ [(Y-X)*100]/X
C.I = 2704-2500 =Rs. 204

7 .

A box contains 2 red, 3 green, and 2 blue balls. What is the probability that none of the balls drawn is blue?

10/19

10/20

10/21

10/23

Correct Answer : 10/21

Explanation :

Total number of balls = (2+3+2) = 7
Let S be the sample space.
Then, n (S) = the total number of ways of drawing two balls out of 7:
= ⁷C₂
= (7*6) / (2*1) = 42/2 =21

Let E is the event of drawing 2 balls, none of which is blue.

n (E) = number of ways of drawing 2 balls out of (2+3) balls.
= ⁵C₂
= (5*4) /(2*1) = 10

So, P(E) = n(E)/n(S) = 10/21

8 .

If the average of three consecutive even numbers is 34, find the largest of these numbers.

Correct Answer : 36

Explanation : Let the first number is x, then the next two even numbers would be x+2, x+4

As per question;
(x+x+2+x+4)/3 = 34
(3x+6)/3 = 34
3x + 6 = 102
3x = 96
x = 32

Largest number would be = 32 + 4 = 36

9 .

A jogger is running at a speed of 15 km/hr. In what time he will cross a track of length 400 meters?

96 sec

100 sec

104 sec

110 sec

Correct Answer : 96 sec

Explanation : Time = Distance/Speed

Distance= 400

Speed = 15km/hr or 15* (5/18) = 75/18 = 25/6 m/s

Required Time =400/(25/6) = 400*6/25 =2400/25= 96 seconds

10 .

A horse covers a distance of 1500 meters in 1 minute and 20 seconds. At what speed the horse is running?

67.2 km/hr

67. 5 km/hr

67.7 km/hr

67.9 km/hr

Correct Answer : 67. 5 km/hr

Explanation : Speed = Distance/Time
Distance = 1500 meters
Time = 1 minute 20 seconds → 60+20=80 seconds
So, Required Speed =1500/80=75/4m/s
We need the answer in km/hr:
So, Speed in km/hr = (75/4)*(18/5) = 67.5 km/hr
