Can you please tell me, why did you take (760,000- 32,000). How did you infer that the laptop price before increase of price would be this?

It is given …..increase by 32000 to 760000.
So final was 760000 after 32000 was added to initial cost.

(760000-32000) = 728000
So, 760/N - 728/(N+6) = 10
By checking from ans. options,
N = 20
Or, solving the equation,
N = 20 [Ans.]
