Posted September 1, 2010 · Report post 1.A triangle is made from a rope. The sides of the triangle are A cm, B cm and C cm. (I do not remember the numerical value). What will be the area of the square made from the same rope? 2.There is a bacteria which has the probability of die 1/3 of its total number or it may tripled. Find out the probability A. P=1/3+(2/3*p^3) B. P=2/3+(2/3*p^3) C. P=2/3+(1/3*p^3) D. P=2/3+(2/3*p^3) I marked it as A. check it out 3.23 men shake hand with each other in a party. Maximum no of handshakes without cyclic handshakes. 4.There are two tanks A,B. A will be fill up 1ltr in one hour. B tank will fill up double in every hour (like 10, 20, 40, 80, 160…..). if the tank B is filled 1/16 in 13 hours how much time it will take to fill up totally. 5.The ages of two friends is in the ratio 5:6. After how many years will the ages be in the ratio 7:8? 6.In a question ,last part has ,the ages of two people has the ratio of 6:6 and by adding the numbers we get 44,after how many years the ratio would be 8:7?

Posted September 6, 2010 · Report post the first one is really vry simple....here's d soln.perimeter of traingle should b equal to perimeter of square as the rope used is same.so, A+B+C= 4x (let x be length of square's side)therefore, x=(A+B+C)/4area of square = x.x = (A+B+C)/4 . (A+B+C)/4 i.e. ur ans. Share this post Link to post Share on other sites

Posted September 6, 2010 · Report post Question no.3 it is analogous to a network topology question ....like what is the no. of connections needed in a full-mesh type of network , where no. of node =23 ??in a full mesh, no og connections = (n.n-n)/2=(23.23-23)/2= (529-23)/2 = 506/2 = 253 Share this post Link to post Share on other sites
