Answer
SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation
I. S.P. of 1 laptop = ₹26250. C.P. of 5 laptops = S.P. of 4 laptops $=₹(26250\times 4)=₹105000$. ⇒ C.P. of 1 laptop $=₹\left(\frac{105000}{5}\right)=₹21000$. Profit earned by selling a laptop $=₹(26250-21000)=₹5250$. So, I alone gives the answer. II. S.P. $=₹26250$, Profit $=25\%$. C.P. $=₹\left(\frac{100}{125}\times 26250\right)=₹21000$.
