Gujrati Second paper

Squared paper.

In an examination, there are 500 students, 150 passed the first paper and 350 passed the second paper. 50 students passed both the papers. Find the probability that a student selected at random has failed in both the papers.

In an examination, there are three papers each of 100 marks. A candidate obtained 53 marks in the first and 75 marks in the second paper. How many marks must the candidate obtain in the third paper to get an overall of 70 per cent marks?

long piece of paper is10 cm wide and is moving uniformly along its length with a velocity of 2 cm//s . An ant starts moving on the paper from point A and moves uniformly with respect to the paper. A spider was located exactly opposite to the ant just outside the paper at point B at the instant the ant started to move on the paper. The spider, without moving itself, was able to grab the ant 5 second after it (the ant) started to move. Find the speed of ant relative to the paper.

Density of the material of a paper is given a 0.5 g cm^(-3) . The mass of the paper is 1 g and its length and breadth are 10 c and 5 cm, respectively. Arrange the following steps in a sequence to find the thickness of the paper. (A). The 0thickness of the paper is ("Volume of the paper (m)")/("Vlume of the paper (V)") (B) The density (d) of the material of the paper is =("Mass of the paper (m)")/("volume of the paper (V)") (C). then the volume (V) o the paper =("Mass of the paper (m)")/("Density (d) of the paper") (D). The volume (V) of the paper is=length xx breadth xx thickness of the paper.

The length of a paper is (3)/(2) times its breadth. If the perimeter of the paper is 80 cm, then find the length and the breadth of the paper.
