Answer 1

Step-by-step explanation:

trees planted by class 5 students = 170 (given)

trees planted by class 6 students = 240 (given)

Trees planted by both of them = 90 (given)

Total trees planted = (170+240)

= 410

Trees planted by 5 and 6 = 90/2 = 45

class 5 = 170-45 = 125

class 6 = 240-45 = 195
