Question

a fruit seller brought mangoes at rupees 90 per dozen and sold them at a loss of 8% how much will cost customer pay for one mango and 40 mangoes

Answer 1

cp for fruit seller = Rs. 90
loss percent = 8

sp = (100 - lp )/ 100 * cp  = (92)/100 * 90 = Rs. 82.8  [ for one dozen of mangoes]
∴ cost of one mangoes = 82.8 / 12  = Rs. 6.90 (ANS)
and, cost of 40 mangoes = (40)(6.90) = Rs. 276 (ANS)
