Question
In a batch of 45 students, the
average programming speed in Python is 80 lines per hour, but after one student left and 8 new students joined, the average programming speed became 79.6 lines per hour. What is the programming speed of a student who codes 6 lines per hour faster than the student who left, if the total programming speed of the eight new students is 620 lines per hour?Solution
ATQ, Total programming speed of batch = 45 * 80 = 3600 3600 - x + 620 = 79.6 * 52 4220 - x = 4139.2 x = 80.8 Required programming speed = 80.8 + 6 = 86.8 lines per hour
