Air required by 10 persons= Volume of cone=18*10=180m3
Area required to stand = 6*10=60m2
So,Volume of cone =area*h/3=180m3
=60*h/3=180
=h=9m

This sue-for-anything philosophy was created in the 1960’s, when judges and legislators woke up to abuses of racism and other discrimination that had gone unchecked for centuries. When the bad values of judges and legislator were finally exposed, they decided to create a neutral system in which no one in authority would assert any values. Give people the right to sue for anything, they thought, and then they can’t blame us for imposing bad values. Pretty soon, every angry person or clever lawyer learned how to demand new “rights”. But these new rights ended up taking away others’ rights.
Trial lawyers justify ruinous claims like a $78,000,000 verdict in Arkansas against a nursing home for the neglect of a 93 years old resident on the basis that it will teach the defendant a lesson not to do it next time. The money, though, comes from you and me, through rapidly rising costs and health insurance premiums. The most important accountability, which the trial lawyers never propose, is to remove the licenses of inept doctors or nursing homes so that they can’t hurt someone else. Trial lawyers, of course, don’t make much money if the focus is on better health care, rather than huge verdicts. A society needs red lights and green lights. The legal system is badly broken. Yet, few efforts at reform have gotten very far.

1) What can be a suitable title for the passage?
A) Positive outcome of law in America B) Misuse of law has shaken faith of Americans
C) Unlawful practice of lawsuits D) Society suffers with the ever-changing legal system.

Let the coins are=2x,3x,5x
Amount=₹2x+₹1.5x+₹1.25x= ₹.4.75x=₹19x/4 =₹.114
x= 114*4/19=24
50p coins are 3x=3*24=72
Hence the amount=₹36.

17 hrs

20 m --------- 50 s -------- 8 h
20x(3/4) m--- 50x(3/4) s---8 h (*Less men=less saplings)
15 m ---------- 75/2 s --------8 h
For 75/2 saplings, 8 hrs, so for 80 saplings = 80x8/(75/2) hrs=256/15 ~ 17 hrs.

Two pumps can be used for pumping corrosive liquid. A pump with a brass impeller costs $1200
and is expected to last 3 years. A pump with a stainless steel impeller costs $2850 will last 5 years.
A rebuild costing $450 will be required after every 2000 operating hours for the brass impeller
pump, while an overhaul costing $1050 will be required for the stainless steel pump after every 8000
hours. It is estimated that the operating cost of each pump is the same at $1.50 per hour. The
company applies a discount factor of 10% to its projects.
For the scenario described below, determine the minimum number of hours per year that the
more expensive pump must be used to justify its purchase. Clearly show the method you have
used. State and comment on any assumptions you have made and the reasonableness of your
method and answer.
