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?
-
24
-
48
-
120
-
144
Correct Answer
A. 48Explanation
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.Rate this question:

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)?
-
1.5 feet
-
3 feet
-
40 feet
-
90 feet
Correct Answer
A. 90 feetExplanation
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.Rate this question:

-
3
-
4
-
8
Correct Answer
A. 8Explanation
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.Rate this question:
