Quantitative Aptitude Questions for IBPS RRB PO and Clerk Exam 2017

Dear Students,

Today we have been including some Boat and Stream.This is the Boat and Stream quiz and you should try to do it within 13-14 Mins. If you fail to complete it in stipulated time, then try again with full force. These quantitative aptitude questions are very important from exam point of view like IBPS RRB Exam, IBPS PO and IBPS Clerk.
