  ## CASELET DI

  • One must be well versed with concepts of Percentages, Ratio Proportion, Fraction simplification, Approximations, Averages in order to solve DI sets.
  • The squares of numbers till 30, cubes till 20 should be known along with percentage values of (1/2), (1/3),…..(1/12).
  • The typical sets are based on questions from Profit Loss, Simple & Compound interest, Production & Consumption, etc.
