SSC CGL question set17 fractions decimals surds

This is the seventeenth question set of 10 practice problem exercise for SSC CGL exam on topic Fractions Decimals and Surds. Students should complete this question set in prescribed time first and then only refer to the corresponding solution set.

We found from our experience that this set of topics together pose some degree of difficulties to the students in a way similar to Algebra. Without going into the reasons behind the difficulties we will try to address them through detailed explanation of efficient problem solutions in the paired solution set.

Before attempting this timed question set, you may like to go through our tutorial article on Fractions and Surds concepts part 1 in which this set of problems was given as an exercise.
