Question

Vinod sold a watch to Arun at a gain of 12% and Arun had to sell it to Manoj at a loss of 5%. If Manoj paid Rs.3990 for it, how much did Vinod pay for the watch?? ​

Answer 1

Answer:

Rs.3750

Step-by-step explanation:

Arun sold watch to Manoj at 5% loss at Rs.3990

$cp = \frac{100}{100 - lose} \times sp$

$= \frac{100}{100 - 5} \times 3990$

= Rs.4200

So, Cost Price of watch for Arun is Rs.4200

Vinod sold watch to Arun 12% gain

$cp = \frac{100}{100 + profit } \times sp$

$= \frac{100}{100 + 12} \times 4200$

$= \frac{100}{112} \times 4200$

= Rs.3750

So, Vinod paid Rs.3750 for a watch.
