B. 2000
Explanation
When the digit 7 in the number 27109 is replaced by 5, the number becomes 25109. The original number was 27109 and the new number is 25109. By subtracting the new number from the original number, we can calculate the decrease in the number. 27109 - 25109 = 2000. Therefore, the number will decrease by 2000.

### 3 feet of film is required to screen 2 seconds of a movie.What is the length of the film required to screen the trailer of Ghajini movie that is of 1 minute(60 seconds)?

• A.

1.5 feet

• B.

3 feet

• C.

40 feet

• D.

90 feet

D. 90 feet
Explanation
To screen 2 seconds of a movie, 3 feet of film is required. Therefore, to screen 60 seconds (1 minute) of the movie, we can calculate the length of film required using the ratio of time to film length. Since 2 seconds require 3 feet of film, we can set up a proportion: 2 seconds/3 feet = 60 seconds/x feet. Solving this proportion, we find that x = 90 feet. Hence, the length of film required to screen the trailer of Ghajini movie is 90 feet.

### Antra calculated  the product of 2222*2223*22*24 and got a number.    what will be the remainder when the product is divided by 10 ?

• A.

2

• B.

3

• C.

4

• D.

8

D. 8
Explanation
When a number is divided by 10, the remainder is the last digit of the number. In this case, the product of 2222*2223*22*24 will result in a large number. However, we only need to find the remainder when divided by 10. Since the last digit of the product is 8, the remainder when divided by 10 will also be 8.

### On the re-opening day of the school, a teacher gave each student in her class containing 3pencils and 2 pens.If she distributed 72 pencils in all, how many pens did she distribute?

• A.

24

• B.

48

• C.

120

• D.

144

B. 48
Explanation
The teacher distributed a total of 72 pencils, which means each student received 3 pencils. Since each student also received 2 pens, the total number of pens distributed can be calculated by multiplying the number of students by 2. Therefore, if the teacher distributed 72 pencils, she must have distributed 2 times the number of students in pens. Dividing 72 by 3, we find that there were 24 students in the class. Multiplying 24 by 2 gives us 48, which is the number of pens the teacher distributed.
