Nothing is invented here, so this question has no answer on record.
Explanation
I. S.P. $=₹7392$. Profit $=12\%$. C.P. of first machine $=₹\left(\frac{100}{112}\times 7392\right)=₹6600$. II. S.P. $=₹7392$. Loss $=4\%$. C.P. of second machine $=₹\left(\frac{100}{96}\times 7392\right)=₹7700$. Total C.P. $=₹(6600+7700)=₹14300$. Total S.P. $=₹(7392\times 2)=₹14784$. Profit $=₹(14784-14300)=₹484$. Thus, I and II together give the answer. ∴ Correct answer is (e).
