Total number of boys in row is 27
Solution:
According to question, Sumit is sitting at 6th Position from left and Raghav is sitting at the 10th position from right.
They swap their position and now Sumit is at 18th Position From left
To Calculate the number of boys in the row we have to calculate number of boys between Raghav and sumit and this can be find in following way:
Number of boys between Sumit and Raghav ={ ( Position of Sumit from Left after swaping) - (Position of sumit from Left before swaping ) } -1
Number of boys between Sumit and Raghav = (18 – 6) - 1 =11
Hence ,
Total number of boys in row = Position of sumit from left + position of raghav from right + number of boys between them
Total number of boys in row = 6 + 10 + 11 =27
