• DI questions needs a lot of concentration because there is given a lot of data and lot of calculations  and do not mix up the data from one question to another
• DI questions may include simple interest and compound interest, percentage , partnership, average , ratio,etc. So if you want to solve DI questions you have to learn all topics, which come in IBPS PO Exam i.e. your basics should be clear.

Some tricks to solve DI questions
