Step-by-step explanation:

Answer 2

Answer: 150

Solution: (2 Approachs)

1. It can be solve by using Arithmetic Progression by taking 1st term as 102 and last as 996. And common difference as 6.

Here, last term - first term = 894 and 894/6=149 and 1 term is first term itself, so total terms will be 150.

2. But I will use shortcut for it, I will divide 100 and 1000 both by 6 and take floor value of it.

So, 100/6 = 16(floor) and 1000/6=166,

So, answer is 166-16 = 150.
