Simplification questions will be ask in two ways, so you all have to know the both types,
  1. The first one is ‘Finding the missing number’.
  2. The second type of simplification question will be ‘the relation between the numbers and simplify the numbers using the rules of simplification’.
Let’s we take the examples with proper explanation:

Directions: Study the following questions carefully and choose the right answer:
