Q1. In a road construction work the average wage per day of 22 labourers is Rs. 100, of 15 drivers is Rs. 120 each and of 13 supervisor is Rs. 150. What is the average of each person?

a) Rs. 120

b) Rs. 119

c) Rs. 150

d) Rs. 140

Ans -[B]

The total wage of 22 labourers = 22 X 100 = 2200
The total wage of 15 drivers = 15 X 120 = 1800
The total wage of 13 supervisors = 13 X 150 = 1950
The total wage of all the persons = 2200+1800+1950=5950
The average wage of each person = 5950/(22+15+13) = 5950/50 = 119

a) 35 years

b) 25 years

c) 21 years

d) 14 years

Directions: Read the passage and answer the items that follow. Your answers to these items should be based on the passage only.

For many people who live in cities, parks are an important part of the landscape. They provide a place for people to relax and play sports, as well as a refuge from the often harsh environment of a city. What people often overlook is that parks also provide considerable environmental benefits. One benefit of parks is that plants absorb carbon dioxide—a key pollutant—and emit oxygen, which humans need to breathe.
Unfortunately, many cities cannot easily create more parks because most land is already being used for buildings, roads, parking lots, and other essential parts of the urban environment. However, cities could benefit from many of the positive effects of parks by encouraging citizens to create another type of green space: rooftop gardens. While most people would not think of starting a garden on their roof, human beings have been planting gardens on rooftops for thousands of years. Some rooftop gardens are very complex and require complicated engineering, but others are simple container gardens that anyone can create with the investment of a few hundred dollars and a few hours of work. Rooftop gardens provide many of the same benefits as other urban park and garden spaces, but without taking up the much­ needed land. Like parks, rooftop gardens help to replace carbon dioxide in the air with nourishing oxygen. They also help to lessen the Urban Heat Island Effect, which can save people money. In the summer, rooftop gardens prevent buildings from absorbing heat from the sun, which can significantly reduce cooling bills. In the winter, gardens help hold in the heat that materials like brick and concrete radiate so quickly, leading to savings on heating bills. Rooftop vegetable and herb gardens can also provide fresh food for city dwellers, saving them money and making their diets healthier. Rooftop gardens are not only something everyone can enjoy, they are also a smart environmental investment.

Q5. Which of the following can be inferred from the passage given above?

a) Cities with rooftop gardens are cooler than those without

b) Some plants are not suitable for growth in rooftop gardens

c) Most people prefer parks to rooftop gardens

d) Most people prefer life in the country over life in the city

Ans- [A]

 

Q6.Which of the following best describes the main difference between parks and rooftop gardens?

a) Parks are expensive to create while rooftop gardens are not.

b) Parks are public while rooftop gardens are private.

c) Parks absorb heat while rooftop gardens do not.

d) Parks require much space while rooftop gardens do not.

Ans- [D]

The author believes that the main difference between parks and rooftop gardens is that parks require much space while rooftop gardens do not. Therefore, (D) is correct.

 

Q7. According to the author, one advantage that rooftop gardens have over parks is that they

a) Decrease the Urban Heat Island Effect.

b) Replenish the air with nourishing oxygen.

c) Do not require the use of valuable urban land.

d) Are less expensive than traditional park spaces.

Ans – [C]

In paragraph, the author contrasts parks, which require the use of valuable land, with rooftop gardens, which do not require any new land. Instead, rooftop gardens can be built on top of existing buildings. Therefore (C) is correct.

 

Q8. Based on information in the passage, it can be inferred that the author would most likely endorse a program that

a) Permitted the construction of buildings in city park land provided they have rooftop gardens

b) Extended discounts on plants to customers who use them to create rooftop gardens

c) Offered free admission to schools willing to take their students on field trips to the city park

d) Promised vacation getaways to cooler destinations for those trapped in the city at the peak of summer

Ans- [B]

In this passage, the author advocates the creation of rooftop gardens. Therefore, it makes sense that he or she would endorse a program that extended discounts on plants to customers who use them to create rooftop gardens. Therefore (B) is correct.
