Numerical Ability for SBI Clerk Prelims 2018
Today is the Day 20 of the SBI Clerk 60 Days Study Plan and the topic for Today’s Numerical Ability or Quantitative Aptitude Practice Questions is Based on Misclleneous. Numerical Ability Section has given heebie-jeebies to the aspirants when they appear for a banking examination. As the level of every other section is only getting complex and convoluted, there is no doubt that this section, too, makes your blood run cold. The questions asked in this section are calculative and very time-consuming. But once dealt with proper strategy, speed, and accuracy, this section can get you the maximum marks in the examination. Following is the Numerical Ability quiz to help you practice with the best of latest pattern questions.
