Q.8. Position of Sita from left is 18th and from right is 30th. Then how many people are in a queue?
Answer : 47
Solution with trick
Note: When a ranking of one person is given; then
[Total no. = rank from left + rank from right – 1
Rank from left = total no. – rank from right +1
Rank from left = total no. – rank from left + 1.]
Total Number = left + right – 1
= 18 + 30 – 1 = 47
Second method:
Total people = 17+1+29 = 47
