400 mangoes were purchased at ₹125 per hundred and sold at a loss of ₹100. Find the S.P. of one dozen mangoes.(7th class math)

Solution:Given,400 mangoes = 125 Rs. per hundred

                           Loss(sell)   = 100 Rs.

 According to question,

 100 mangoes -------- 125 Rs.

 400 mangoes --------- 125 x 4 = 500 Rs. = C P

 and sold at a loss of Rs.100.

 then,400 mangoes -------- 500 - 100 = 400 Rs. = S P

 1 mangoes -------- 400/400 = 1 Rs.

question Find the S P of one dozen mangoes.

 then ,12 mango --------- 12 Rs.
