Re: Bank PO Techniques to solve Maths questions
As per your request, I am giving you some tips to quick solve the maths question which is useful in bank PO exam. Squaring Find square of 43 = (43+3) * (433) + (3*3) =(46*40) + 9 = (460*4) + 9 = 1840 + 9 = 1849 Multiplication Multiply 62 with 32 Square root Find square √ 1936 √ 1936 = √ 4 * √ 484 = √ 4 * √ 4 * √ 121 = 2*2*11 = 44 Time and Work For example  A takes 10 days to complete a job. B takes 20 days to complete the same job. In how many days they will complete the job if they work together ? A's efficiency = 100/10 = 10% per day B's efficiency = 100/20 = 5% per days A and B can do 15% of the work in a day if they work together. So they can do the whole job in 100/15 = 6.66 days or 6 days and 18 hours.
