Answer:

Sale price of Badarpur sand per bag = Rs. 29.68

purchase price of cement per bag = Rs.103.89

Step-by-step explanation:

Given :

A builder sells 70 bags of Badarpur sand  at 15% sales commission.

then he purchases 17 bags of cement from the amount remained after deducting his commission. And its purchase commission is 5%.

totally he received Rs.400.

To find:

price of Badarpur sand per bag and purchase price of cement per bag.

solution:

Let total amount of sale price of Badarpur sand be x and total amount of purchase price of cement be y.

sales commission = 15% of sale price = 15% of x

purchase commission = 5% of purchase price = 5% of y

as given , x - 15%of x =y

          x- 15 × x =y                                        

             100

100x-15x = 100y ⇒ 85x -100y = 0 ------eq.(1)

Also he receives 400 as commissions,

15%x+5%y =400

15 × x + 5   × y =400

100        100

15x + 5y = 400×100= 40000

15x +5y = 40000 -----eq.(2)

solving eq.(1) and eq.(2) we get.

 85x-100y = 0

300x+100y = 800000    (multiply eq.(2) by 20)

385x          =800000

x = 800000/385 = Rs.2077.9

put x value in eq.(1) ⇒ 85× 2077.9 -100y = 0

                                ⇒176621.5 = 100y

                                 y = 176621.5/100= Rs. 1766.2

sales commission =15%x = 15 ×2077.9 = 31168.5/100 = Rs. 311.69

                                           100

purchase commission = 5% y = 5 ×1766.2 =Rs. 88.31

                                                   100

Therefore,

sale price of Badarpur sand per bag = 2077.9/70 = Rs.29.68

   purchase price of cement per bag = 1766.2/17 =  Rs.103.89
