Answers
Answer:
Ans is 9.
Step-by-step explanation:
Kashi was 17th from right..
When they switched their positions Kashi became 27th.
Therefore between them are 18,19,20,21,22,23,24,25,26.
counting them is total 9 students.
9 students
Rakesh is 12th from the left.
That is, he has 11 students on his left.
After Rakesh and Kashi interchange their positions, Kashi is in the 27th position from the right.
Thus, Rakesh had 26 on his right.
Therefore,
Total number of students = number of students in his left+himself+number
of students in his right
= 11+1+26
= 38
Rakesh is in 12th position from left
Kashi is in 17th position from right
Number of students between them = 38-(12+17)
= 38-29
= 9
Or
After interchange,
Rakesh is in 22nd position
Kashi is in 12th position
Number of students between them are 13, 14, 15, 16, 17, 18, 19, 20, 21
Number of students between them = 9 students
