I am sharing my experience on “Objective Arithmetic”by R. S. Aggarwal which is one
of the best book for competitive examinations. It is beneficial for those who are looking for jobs in government services like Bank PO, SSC, Specialist Officers, RBI, SBI , PO, Railway, LIC, GIC, UPSC, Income Tax etc. The entire book cover chapters like simplification, Average, Problems on Age, Profit & Loss, Ratio &proportion, Time & work, S.I & C.I, Time & distance, Area, Trigonometry, Percentage, Boat & Stream, Calender, Clocks, Geometry, Height and distance etc.
All the chapters having important fact and formula with solved examples so that you can solve problem easily. Exercise questions from each chapter contains questions that have been asked in previous competitive examinations that can help you to reach to that level of examinations. Overall it is one of the best book for competitive examinations and I like it.
