An urgent message had to be delivered from the house of the Peshwas in Pune to Shivaji who was camping in Bangalore. A horse rider travels on horse back from Pune to Bangalore at a constant speed. If the horse increased its speed by 6 km/h, it would take the rider 4 hours less to cover that distance. And travelling with a speed 6 km/h lower than the initial speed, it would ake him 10 hours more than the time he would have taken had he travelled at a speed 6 kmph higher than the initial speed. Find the distance between Pune and Bangalore.

There is a circle of radius 1 cm. Each member of a sequence of regular polygons S1(n), n = 4, 5, 6, …, where n is the number of sides of the polygon, is circumscribing the circle: and each member of the sequence of regular polygons S2(n), n = 4, 5, 6, … where n is the number of sides of the polygon, is inscribed in the circle. Let L1(n) and L2(n) denote the perimeters of the corresponding polygons of S1(n) and S2(n), then {L1(13) + 2π}/L2 (17) is
a. greater than 4 π and less than 1
b. greater than 1 and less than 2
c. greater than 2
d. less than 4
Please help! What would be the solution to this?
If there are 3 mixtures -
1 having water and coffee in the ratio 1 : 2,
2nd having water and tea in the ratio 1 : 3, and 3rd having
water and juice in the ratio 1 : 4.
All these mixtures are further mixed together in the proportion 4 : 3 : 2. Then the resulting mixture has
- The same amount of water and tea
- The same amount of tea and juice
- More water than tea
- More water than coffee

Anusha, a teacher, conducted an exam for five students, Pavan, Kiran, Gaurav, Sravan and Ram. Each student received a different mark in the exam and Anusha ranked the five students from 1 to 5 based on their marks in the exam such that a numerically lower rank is considered better than a numerically higher rank. However, before revealing their ranks to the five
students, she asked each of them to guess the ranks of all the five students.
The following information is known about the ranks guessed by the five students:
i.Except for Pavan, none of the students guessed that the rank of Gaurav would be better than that of Ram.
ii.None of the students correctly guessed the actual rank of any student and no student guessed their rank to be worse than third.
iii.Except for Kiran, none of the students guessed their own rank to be one, while no student guessed that the rank of Pavan will be better than third.
iv.Except for Ram and Gaurav, none of the others guessed that Sravan would be ranked third, and Ram guessed Pavan’s rank to be four.
v.Except for Kiran, the rank of each student was guessed to be five by at least one student, while Sravan guessed the rank of Ram to be less than four.
vi.Kiran guessed that Pavan would be ranked better than Gaurav, while Pavan guessed Gaurav would be ranked first.
vii.Sravan guessed the rank of the student whose actual rank was five to be one, and the rank of the student whose actual rank was three to be five.
Question: How many students guessed the rank of Kiran to be 1?

Ravi, who lives in the 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 hiswife, forewarned of his plan, had met him at the station?
