Question
Darwin chapelle is 15th from the left end of a row of 30 students and Monika srivastav is 20 th from the right end in the same row. How many students are there between them in the row?
Solution
To solve this problem, we first need to understand the positions of Darwin Chapelle and Monika Srivastav in the row.
-
Darwin Chapelle is 15th from the left end of a row of 30 students. This means there are 30 - 15 = 15 students to the right of Darwin.
-
Monika Srivastav is 20th from the right end of the row. This means there are 30 - 20 = 10 students to the left of Monika.
-
Now, we need to find out if there is an overlap in their positions. If the sum of the number of students to the right of Darwin and the number of students to the left of Monika is less than or equal to the total number of students, then there is no overlap and the sum will give us the number of students between them.
-
The sum of the number of students to the right of Darwin and the number of students to the left of Monika is 15 + 10 = 25.
-
Since 25 is less than 30, there is no overlap in their positions. Therefore, there are 25 students between them in the row.
