C-1) Indian Airlines operates non-stop flights between Guwahati and Dubai, which are separated by an aerial distance of 3000 kilometres. Guwahati is located east of Dubai and both of them are in different time zones. Indian Airlines has a certain free luggage allowance and charges for excess luggage at a fixed rate per kg. Two students from Dubai, Aasma and Shaariq chose to visit Guwahati for the purpose of taking part in Technothlon. They returned by flight after three days of thrill and enjoyment, taking back with them many prizes and lifetime memories. They had 60 kg of luggage between them, and were charged Rs 1200 and Rs 2400 respectively for excess luggage on their way back to Dubai. Had the entire luggage belonged to one of them, the excess luggage charge would have been Rs 5400. Their journey schedule was as given below: Arrival day Dubai Guwahati 8.00 am 3.00 pm
Departure day Guwahati Dubai 4.00 pm 8.00 pm
Assume that planes cruise at the same speed in both the directions. However, the effective speed is influenced by a steady wind blowing from east to west at 50 km per hour. Now answer the following questions based on this passage:

Formula One, abbreviated to F1, is the highest class of Auto racing sanctioned by the Fédération Internationale de l’Automobile (FIA). The F1 World Championship season consists of a series of races, known as Grande Prix, held on purpose-built circuits.
Formula-One cars race at high speeds, up to 360 km/h with the engine revving up to 19,000 RPM. The cars are capable of pulling 5g in some corners. The average speed of a F-1 car while turning is about 200 km/p and in the pits it is about 80 km/h.
Early designs linked wings directly to the suspension, but several accidents led to rules stating that wings must be fixed rigidly to the chassis. The cars’ are aerodynamically designed. The FIA is hoping to rid F1 of
small winglets and other parts of the car (minus the front and rear wing) used to manipulate the airflow of the car.
The fuel used in F1 cars is fairly similar to ordinary gasoline, albeit with a far more tightly controlled mix. Formula One fuel can only contain compounds that are found in commercial gasoline.
By regulation, the tyres feature a minimum of four grooves in them. Since the start of the 2007 season Bridgestone is the sole tyre supplier and have introduced four compounds of tyre, two of which will be made available at each race.
Here’s are fun fact for all of you F-1 fans out there, The acceleration of a F-1 car is usually 1.45 g (14.25 m/s²) up to 200 km/h (124 mph), which means the driver is pushed back in the seat with 1.45 times his bodyweight.
Q1. What is the need for wings in a F-1 car?
a.) To create maximum downward force and minimum drag
b.) To create minimum downward force and minimum drag
c.) To create minimum downward force and maximum drag
d.) To create maximum downward force and maximum drag
Q2. What is the average speed of a formula one car? (Assuming that the average time spent on the tracks is 20mins, cornering time is 10mins and pit stop time is 5mins.)
a.) 274 km/h
b.) 200 km/h
c.) 260 km/h
d.) 280 km/h
Q3. While cornering the magnitude of average force experienced by the formula 1 driver is about 5.5g – 7g. Which of these forces causes this?
a.) Force of gravity.
b.) Force of wind acting against the driver
c.) Force directed towards the centre
d.) Force directed away from the centre
Q4. What is the use of extra treading in F-1 cars?
a.) To increase friction and improve grip
b.) To decrease friction and improve grip
c.) To increase friction and reduce wear and tear of the tyre
d.) To decrease friction and reduce wear and tear of the tyre
Play with Numbers
1. There is a four digit number, which when written in reverse order, becomes 4 times itself. Find the number.
2. You have a truck which has a full tank of 10 litres. You also have two 45 litre barrels of fuel. In order to make room for the load carried by the truck, only one of the barrels can be carried at a time. While you can’t transfer fuel between barrels, you can refill the tank from the barrels. Assume that the truck can get 12 miles per litre, regardless of the load it carries. What is the maximum distance you can cover? (Assume that the truck can go forward or backward at any point of time and, while you are driving you know the exact amount of fuel which is left in the fuel tank at that moment.)
3. A 8-digit number is such that its 1st digit specifies the number of zeroes, 2nd digit specifies the number of ones and so on. Find the number.
4. Four children were asked to think of a four digit number each. They were then asked to put the last
digit of the number in front and add the new number (so formed) to the original number (for
example: 3412+2341=5753). They wrote down their results as:
Everyone except one had written the wrong answer! Who answered correctly?
5. Mr. and Mrs. Srivastava threw a dinner party, and invited four other couples: the Shobhanes, the
Patnis, the Mukherjees, and the Umbarkars. When all the guests had arrived there were ten people in the house. Some of these people had met before and some hadn’t. All the people who had never met before shook hands. Then Mr. Srivastava asked every guest and his own wife how many hands each of them had shook. To his surprise every person gave a different answer. How many hands did Mrs. Srivastava shake?
