Solution(By Examveda Team)

$$\eqalign{ & {\text{Profit}}\% = 25 \cr & 25\% = \frac{1}{4} \cr & {\text{CP}}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{\text{SP}} \cr & \,\,\,4\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,5 \cr & \,\,\,\,1 - - - 210 \cr & \therefore {\text{SP}} = 210 \times 5 \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 1050 \cr} $$

Alternate Solution :
Let Cost price is 100x
Then Selling price is 125x
According to the question,
Selling price - Cost Price = 210
⇒ 125x - 100x = 210
⇒ x = $$\eqalign{ \frac{210}{25} \cr }$$
So the Selling price → 125x
= 125 × $$\eqalign{ \frac{210}{25} \cr }$$
= Rs. 1050
