Total number of students going to a trip = 210
Each students was given 1 orange, 1 banana and 5 biscuits.
Number of oranges distributed to 210 students = 1 × 210 = 210
38 students refused to take bananas.
So, number of students who took bananas = 210 – 38 = 172
Hence, number of banans distributed = 1 × 172 = 172
Number of biscuits distributed to 210 students = 210 × 5 = 1050
Thus, 210 oranges, 172 bananas and 1050 biscuits were distributed among all the students going to the trip.
