Question

bashir bought an article for Rs 1215 and spent 35 Rs on its transportation at what price should he sell the article to have a gain of 16%

Answer 1

cost price of article = Rs 1215

transportation charges = Rs 35

total cost price (c.p)= 1215+35= 1250

gain= (g)=16%

selling price = cp(100+g)/100

= 1250(100+16)/100

= 1250*116/100
= Rs1450

Answer 2

Cost price of article           =  $$1215$
Transportation charges     =  $$35$
∴ Net buying price            =  $$(1215+35)$
                                             =  $$1250$  

If profit is 16%,

We know, 
   Sell Price =  Buying Price + Profit
                      =  $$[1250+( \frac{16}{100}*1250)]$
                      =  $$[1(1250)+ \frac{4}{25}(1250)]$
                      =  $$[1250(1+ \frac{4}{25} )]$
                      =  $$[1250( \frac{25+4}{25} )]$
                      =  $$[ 1250*\frac{29}{25}]$
                      =  $$(50*29)$
                      =  $$1450$   (ans.)
