In this article, The expert SSC team of www.jagranjosh.com has prepared a set of 25 questions covering the Mathematical Operations of type-1 for Reasoning section. There are 2-4 questions in SSC CGL out of this chapter. We are providing you different variety of questions based on Type-1 which will surely help you in scoring good marks.

There are basically four fundamental operations, i.e. Addition, Substraction, Divison, Multiplication and apart from that ‘Greater than’,’ smaller than’,’ equal to’ & ‘not equal to’. While solving the problems, you must keep the **BODMAS **Rule into consideration, i.e. Brackets, Of, Division, Multiplication, Addition, Subtraction.

Apart from that, there are basically 4 types of problems in Mathematical Operations.

- Problem solving by substitution
- Equation Balancing
- Interchanging Signs and numbers
- Trick based Mathematical Operations

Here are the practice questions. Go through it.
