There are three cities A, B and C, each of these cities is connected with the other two cities by at least one direct road. If a traveller wants to go from one city (origin) to another city (destination), she can do so either by traversing a road connecting the two cities directly, or by traversing two roads, the first connecting the origin to the third city and the second connecting the third city to the destination. In all there are 33 routes from A to B (including those via C). Similarly there are 23 routes from B to C (including those via A). How many roads are there from A to C directly?
OA is 6. Plz provide an explanation.
There are six positive integers such that
A
How many triplets can be formed such that the first number is less than each of the second and third number of that triplet.

Please provide a properly explained solution to this question..Ravi, who lives in a countryside, caught a train for home earlier than usual yesterday. His wife normally drives to the station to meet him. But yesterday he set out on foot from the station to meet his wife on the way. He reached home 12 minutes earlier than he would have done had he waited at the station for his wife. The car travels at a uniform speed which is 5 times Ravi's speed on foot. Ravi reached home at exactly 6 o'clock. At what time would he have reached home if his wife, forewarned of his plan, had met him at the station?

Directions for Question 2 : Answer the question on the basis of the information given below. A boy goes from his house to his school daily by a motorbike. He drives the motorbike at three different speeds 'a', '2.5a' and '4a' km/hr for three different durations during the journey. He definitely knows the time intervals for which he should drive his motorbike at each of these speeds so as to reach the school on time.
Q.2 Usually the time for which the boy drives at 'a' km/hr, '2.5a' km/hr and '4a' km/hr is in the ratio 2:1:3. If this ratio becomes 4:1:1, the boy reaches 30 minutes late. Find by how much time (approximate) the boy will be late to school if this ratio is 3:2:1?
a11.7 minutes
b14.6 minutes
c19.7 minutes
d14.3 minutes
