How many people are there in the theater?

Answer: Option E

Explanation:

If Sujit entered before Suraj then the number of people will be 15 + 1(Sujit) + 7 + 1(Suraj) + 20 = 44.

If Suraj entered before Sujit then number of people will be 7 + 1(Suraj) + 7 + 1(Sujit) + 12 = 28.

So, the number of people in the theater cannot be determined.

Explanation:

Between B and E there are two intermediary stations C and D. For traveling from B to C, from C to D and from D to E it takes 3 * 25 = 75 minutes. At each of C and B it halts of 5 minutes. Hence, the time taken to reach E after starting at B is 85 minutes. i.e. one hour 25 minutes. Hence, it started at 7:30 at B. =>it reached B at 7:25.

5. P, Q, R, S, T and U are six cities which are in a row in the same order. A bus, b1 travels from P to U and another bus b2 travel from U to P.

Answer: Option C

Explanation:

The bus b1, which started at P, reached S at 10:40, passing through the intermediary cities Q and R.

The time taken to travel from P to S

= 3 * 40 + 2 * 15 = 150minute

(journey)+(stoppage)
= 2 hrs 30 minutes.

Hence, b1 started at 10:40 - 2:30 = 8:10 at P.

b2 reached Q, starting at U, through the city T, S and R.

The time taken by it to reach S = 4 * 40 + 3 * 15 = 205 minutes
= 3 hr 25 minutes.

Hence, b2 started at, 10:35 - 3:25 = 7:10, at U.
