- Position of emma is fixed that is 36th from left .
Statement 2) :- Peter sat 20 places to the left of Emma.

- Peter = 16th from left .
- 4 girls between Peter and Amy = Peter , 1, 2, 3, 4, Amy Or, Amy, 1, 2, 3, 4, Peter .
- Amy = 16 + 4 + 1 = 21 from left .
- Or, Amy = 16 - 4 - 1 = 11 from left .
Statement 4) :- Amy was made to sit 20 places to the right of Rose .
