    Explanation

    The mangoes are bought at the rate of 6 for Rs 5 and sold at the rate of 5 for Rs 6 .Let the number of mangoes purchased be, LCM of 6 and 5 = 30 Cost price (CP) of 30 mangoes =30  ×  56=25  Rs= \frac{{30\; \times \;5}}{6} = 25\;Rs Selling price (SP) of 30 mangoes =(  30  ×  6)5=36  Rs.= \frac{{\left( {\;30\; \times \;6} \right)}}{5} = 36\;Rs. Loss or gain percent =∣  CP−SP∣CP×100  %= \frac{{\left| {\;CP - SP} \right|}}{{CP}} \times 100\;\% Since CP < SP, hence there is a gain. Gain percent =  36−2525  ×  100  =  1125  ×  100  =  44  %= \;\frac{{36 - 25}}{{25}}\; \times \;100\; = \;\frac{{11}}{{25}}\; \times \;100\; = \;44\;\%
