As train running at 54 kmph takes 20 seconds to pass a platform.Next it takes 12 seconds to pass a man walking to 66kmph in the same direction in which the train is going.Find the length of the train and the length of the platform.

Two trains A & B are travelling in the same direction at a certain speed. Length of the train A is 300 metres and the speed of the train B is 30km/hr. The train A passes a man who is walking at a speed of 4km/hr along the line in the same direction as 'A' in 30 seconds. If the train A passes the train B completely in 5.4 minutes find the length of the train B in metres?

The bar graph shown in Figure represent the circulation of newspapers in 10 languages. Study the bar graph and answer the following questions: What is the total number of newspapers published in Hindi, English, Urdu, Punjabi and Bengali? What percent is the number of news papers published in Hindi of the total number of newspapers? Find the excess of the number of newspapers published in English over those published in Urdu. Name two pairs of languages which publish the same number of newspapers. State the language in which the smallest number of newspapers are published. State the language in which the largest number of newspapers are published. State the language in which the number of newspapers published in between 2500 and 3500. State whether true or false: The number of newspaper published in Malayalam and Marathi together is less than those published in English. The number of newspapers published in Telugu is more than those published in Tamil.

A driver having a definite reaction time is capable of stopping his car over a distance of 30 m on seeing a red traffic signal, when the speed of the car is 72 km/hr andover a distance of 10 m when the speed is 36 km/hr. Find the distance over which he can stop the car if it were running at a speed of 54 km/hr. Assume that his reaction time and the deceleration of the car remains same in all the three cases.

Two balls of the same radius and weight are suspended on threads so that their surface are in contact. A charge of q_(0) = 4 xx 10^(-7)C is given to the balls which makes them repel each other and diverge to an angle of 60° . Find the mass of the balls if the distance of balls from the point of suspension to the centre of ball is 20cm. Find the density of the material of the balls if the angle of divergence becomes 54° when the balls are immersed in kerosene of density 800kg m^(-3) dielectric constant ofkerosene is epsilon_(r) = 2 [1.592g, 255 K//g m^(3)]
