Topic of the Week (Quantitative Aptitude): Simplification (10 Questions)

Hi Readers,

Simplification is one of the most frequently asked topics in the Quantitative Aptitude section. At least 5 Questions can be seen in the Prelims of Bank PO as well as Bank Clerical exams. Therefore, it is essential to have a firm grip on this topic. To be good in simplification you need to have a basic understanding of Calculation (BODMAS).  Apart from that, to increase your calculation speed you must also have good knowledge of tables (up to 25) as well as Squares and Cubes. After this, Practice as much as you can to decrease your calculation time in the exam. To assist you with this, today I have come up with 10 questions of simplification along with the detailed solution.

These questions are very important from the exam point of view. The following are 10 questions of simplification which are expected to be solved under 10 minutes. Set a timer and evaluate your speed as well as accuracy and try to improve accordingly.
