Solution

The correct option is A 14.78%
S.P of first article = Rs. 640
Profit =20%
Then C.P of the first article =100100+20×640= Rs. 533.33
S.P of second article= Rs. 640
Profit =10%
Then C.P of the second article =100110×640=581.81
Total S.Pc =640+640= Rs. 1280
Total C.P =533.33+581.81= Rs. 1115.14
S.P. > C.P.
Therefore, profit =12801115.14= Rs. 164.86
Profit % =164.861115.14×100=14.78%
