Answer: Option A

Explanation:

Each element of the array represents the maximum number of steps that can be taken forward from that element. So as the first element here is 0 so we cannot move any further from the first element. Thus, it is not possible to reach the end of the array.

Read the passage and answer the questions that follow on the basis of the information provided in the passage.

 Environmental toxins which can affect children are frighteningly commonplace. Besides lead, there are other heavy metals such as mercury, which is found frequently in fish, that are spewed into the air from coal-fired power plants, says Maureen Swanson, MPA, director of the Healthy Children Project at the Learning Disabilities Association of America. Mercury exposure can impair children's memory, attention, and language abilities and interfere with fine motor and visual spatial skills. A recent study of school districts in Texas showed significantly higher levels of autism in areas with elevated levels of mercury in the environment. Researchers are finding harmful effects at lower and lower levels of exposure, says Swanson.
They're now telling us that they don't know if there's a level of mercury that's safe. Unfortunately, some of these chemicals make good flame retardants and have been widely used in everything from upholstery to televisions to children's clothing. Studies have found them in high levels in household dust, as well as in breast milk. Two categories of these flame retardants have been banned in Europe and are starting to be banned by different states in the United States. The number of toxins in our environment that can affect children may seem overwhelming at times. On at least some fronts, however, there is progress in making the world a cleaner place for kids and just possibly, reducing the number of learning disabilities and neurological problems.With a number of efforts to clean up the environment stalled at the federal level, many state governments are starting to lead the way.And rather than tackle one chemical at a time, at least eight states are considering plans for comprehensive chemical reform bills, which would take toxic chemicals off the market.

"Besides lead, there are other heavy metals such as mercury, which are found frequently in fish, that are spewed into the air from coal-fired power plants". How can this line be worded differently.


ABesides lead, mercury is another heavy metal which is found frequently in discarded fish cooked in coal-fired power plants.

BBesides lead, fish contains mercury which is a heavy metal ejected in the air from power plants using coal.

CFish, contains mercury which is released in the air as industrial waste and which is also a heavy metal like lead.

DMercury relaeased in the air as industrial waste is another heavy metal like lead, found in fish.

Choose the correct option.

If the cost price of 20 articles is equal to the selling price of 16 articles, What is the percentage of profit or loss that the merchant makes?


A15% Profit

B25% Loss

C25% Profit

D15% Loss

Answer: Option C

Explanation:

Let Cost price of 1 article be Re.1.
Therefore, Cost price of 20 articles = Rs. 20.
Selling price of 16 articles = Rs. 20
Therefore, Selling price of 20 articles = (20/16) * 20 = 25
Profit = Selling price - Cost price
= 25 - 20 = 5
Percentage of profit = Profit / Cost price * 100.
= 5 / 20 * 100 = 25% Profit

 View Answer |  Submit Your Solution | Important Formulas | Topic: Percentage | Asked In HCL TechnologiesSSC CGL Tier I |

Answer: Option D

Explanation:

Let total population = p
no. of males =5p/9
no. of females =(p-5p/9)=4p/9
married males = 30% of 5p/9=30*5p/100*9 =p/6
married females = p/6
unmarried females =(4p/9-p/6)=5p/18
%age of unmarried females in the total population = {(5p/18)/p}*100= 250/9% = 27.78%
