Question

The class mark of a particular class is 6 5 and it's class size is
3 Write the next 3 classes If they are continuous

Lovina Kansal · Accepted Answer

Class mark = 6 5 Class size = 3 If the class interval is a– b, then class mark

and class size = b – a Here,

⇒ a + b = 13 and a – b = – 3 On solving above two equations, we get a = 5 and b = 8 Thus, class interval is 5 – 8 So, the next 3 classes are 5-8,8-11,11-14 Regards Dear student
