Vanita bought a watch with 25% discount on the selling price. If the watch cost her Rs. 780, What is the original selling price of the watch?

1Rs. 950
2Rs. 1000
3Rs. 1040
4Cannot be determined

Answer:- 1

Explanation:-

Solution:

Let the original S.P. of the watch be Rs. x.
Then,

\begin{aligned} = 75 % of x = 780 \\ \Rightarrow x = (\frac{780 \times 100}{75}) \\ = 1040. \\ = Rs . 1040. \end{aligned}

$\eqalign{ & = 75\% {\text{ of }}x = 780 \cr & \Rightarrow x = \left( {\frac{{780 \times 100}}{{75}}} \right) \cr & \,\,\,\,\,\,\,\,\,\,\,\,\, = 1040. \cr & = {\text{Rs}}{\text{. }}1040. \cr}$
