Profit % = (Selling price - cost)/cost*100 =60-c/c = 0.32 =>1.32 c =60 => c=45.45

Profit percentage had he eaten 6 chocolates and sold the remaining 4 chocolates for Rs.48. = 3/45.45*100=6.6

1.32 x Price per chocolate(P) x 8 = 60
=>P = 60/(8 x 1.32)

Let the new profit percent be x.
(1 + x/100) x P X 4 = 48
From the above 2 equations:-
[spoiler]
x = 5.6% which is D.[/spoiler]
It takes time and effort to explain, so if my comment helped you please press Thanks button :)

Selling price of 8 chocolates = Rs. 60.
Since Mr. X made a profit of 32%, the cost price of 10
chocolates = Rs. (6000/132) = Rs. (500/11)

Selling price of 4 chocolates = 48.

Profit percent = (48 - 500/11)/(500/11) x 100 = 5.6%
