In an objective paper, there are two sections of 10 questions each.For "section 1", each question has 5 options and only one optionis correct and "section 2" has 4 options with multiple answers and marks for a question in this section is awarded only if he ticks all correct answers. Marks for each question in "sectionl 1" is 1 and in "section 2" is 3. (There is no negative marking.) If a candidate in total attempts 4 questions by guessing ,then the probability of scoring 10marks is

In an examination, mark obatined by Rohan in two subject are x and y. The total marks in the two subjects is less than or equal to 150. The maximum of marks of each subject is 100. Find the sum of the minimum and the maximum values of 3x+4y. ( No negative marks in the examination )

A body weight 45 kg wt on the surface of earth. Its weight on the surface of Mars will be [Mass of Mars = (1/9) mass of earth, Radius of Mars = (1/2) Radius of earth]

A body weighs 63 kg-wt on the surface of earth. Its weight on the surface of Mars will be (Mass of Mars = 1/9 mass of earth, Radius of 9 Mars = 1/2 Radius of earth)

A body weighs 63 kg-wt on the surface of earth. Its weight on the surface of Mars will be (Mass of Mars = 1/9 mass of earth, Radius of 9 Mars = 1/2 Radius of earth)

A rocket is fired vertically from the surface of Mars with a speed of 2kms^(-1) . If 20% of its initial energy is lost due to Martian atmospheric resistance, how far will the rocket go from the surface of Mars before returning to it? Mass of Mars =6.4xx10^(23)kg , radius of Mars =3395 km ,
