# IBPS RRB 2018 Prelims : Quants – Day 12

Dear Bankersdaily Aspirants,

IBPS RRB PO & Office Assistant 2018 Preliminary Examination starts from 11th August, 2018. The IBPS RRB Exam 2018 is one of the most expected exam of the year. The reason for the consummate expectation is different from that of the others.

The number of candidates attending the IBPS RRB PO & Office Assistant is high when compared to the other exams like SBI & Insurance Exams. The other important factor is that , no English section is there in the preliminary examination of the IBPS RRB PO & Assistant Exams. This is really a boost to the candidates as many of the aspirants couldn’t get the requisite marks in the English section and this exam is the best bet for the aspirants.

Since only few days are left for the IBPS RRB PO & Assistant Exam 2018 Preliminary Exam , we will be providing daily 20 Questions in Quantitative Aptitude & Reasoning Section to evoke the preparation mode.

Aspirants can answer the Questions by commenting the answers for the Questions in the comments section. We will be providing the answers for the Questions @ 6:00 P.M everyday.
