1 Step To Success Tutorials Class X ( Widen your knowledge horizons ) . Mathematics Formulae & some basic concepts Compound Interest Sales S.I = PRT/100 Amt = P ( 1 + Rate/100 )Time i.e. A = P ( 1 + R/100 )n (where Time or n is no. of years) Note : If you are asked to compute the interest semi-annually ( Half yearly) the above formula is to be modified, by taking time 2, and (rate/2) , A = P ( 1 + R/200 ) n (where n is no. of years) If the rates are given differently for the consecutive years, then For example if the rates are 8 % , 12 % and 15 % respectively, then Amt = P ( 1 + 8/100 ) ( 1 + 12/100 ) ( 1 +15/100 ) (Here, you need not mention time as exponent.) Depreciation Certain item s value get diminished as time passes, then it is known as depreciation. For example the value of a car, refrigerator, machinery etc. in that case: Final Value of machine = Initial value ( 1 Rate/100 )Time In population growth problems, If present population is given and asking for i) The population n yrs ago, then take Amount as Present population , and find Principal ii) The population after n yrs, then take Principal as Present population , and find Amount Tax & VAT Selling price = Marked price + x % of sales tax. OR S.P. = M.P.( 1+ST% / 100 ) Selling price = Marked price x % Discount . OR S.P.= M.P. ( 1- D% / 100 ) Selling price = M.P. ( 1- D% / 100 ). ( 1+ST% / 100 ) ( when sales tax and discount both are given ) Tax % =( Tax / M.P.) x 100 Discount % = ( Discount / MP.) x 100 While computing VAT In step1 : Take manufacturing cost and Calculate VAT on Manufacturing Cost In step2 : Take Profit 1, and Calculate VAT on Profit 1 only In step3 : Take Profit 2, and Calculate VAT on Profit 2 only In step4 : Take Profit 3, and Calculate VAT on Profit 3 only . (+) Add all to get Total VAT Selling price = Manufacturing cost +Profit 1 +Profit 2 + Profit 3 etc., + Total VAT Banking Savings Bank account : While taking the entries you have to bear in mind that While computing the interest always take time as 1/12, irrespective of the total number of months given. i.e in PRT / 100, take time as 1/12, instead of total no of months.
