He decides to make a profit of 5.36% on the sale of goods worth Rs.5000 and increase the proit percent by 3.14% for sales upto 215000 and then increase the profit percent for the sale of remaining lot such that he is able to make a profit of 25% on the sale of the full lot. Then profit that he makes on the third lot of goods is

A.

Rs.5620

B.

Rs.4512

C.

Rs.3212

D.

None of these

 

Answer : B

Explanation :

C.P. of goods for the trader = Rs.22520
S.P. = 125 x 22520 = Rs.28150
∴ Profit =  Rs.5630
Now, 5630 = 0.0536 x 5000 + 0.085 x 10000 + (x/100)* 7520 
=>5630 =268 - 850 + 75.2x 
=>75.2x = Rs.4512, which is nothing but profit from sale of third lot.
