Let initially the number of women be \(w\). hence, the number of men in the bus be \(2w\).
At stop Y, 5 women board while 10 men leave,
Then,
\(w+5 = 2w - 10\)
\(⇒ w = 15\)
Thus, the total number of passengers at the beginning of the day,
\(w + 2w\)
\(⇒ 45\)
So, the correct option is (D): \(45\).
A, B, C, D, E, F and G are travelling in three different vehicles: Swift, Creta, and Nexon. There are at least two passengers in each vehicle. Among them, only two are male. There are two engineers, two doctors and three teachers.

(iii) D is a male doctor.
(iv) Two persons belonging to the same profession do not travel in the same vehicle.
(v) A is not an engineer and travels in a Creta.
