**Dear students,**

**Numerical Ability for SBI Clerk Prelims 2018**

Today is the

**Day 47 of the SBI Clerk 60 Days Study Plan**.**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.
