APTITUDE TEST:

Enlish: 32 Q,20M

10 -synnonym

10-antonym

I got anly 4 common .

For antonym U prepare from all Model test parer of barron 12 . Don’t wast time for preparing synnonym becoz there are lots of synnonym so u can,t collct all synnonym.

6-fill in the blank .Exatly this fill in the blank came in my paper.

2. FILL THE BLANKS:

Observe the dilemma of the fungus; it is a plant, but possesses no chlorophyll. While all other plants put the sun’s energy to work for them combining the nutrients of ground and air into the body structure._____1______.Chlorophyll is found in these other plants which, having received their energy free from the sun, relinquish it__2__.

In this search of energy, the fungus has become the earth’s major source of rot and decay. Wherever you see mould forming on a piece of bread, or a pile of leaves turning to compost, or a bloom down tree becoming pulp on the ground, _____3___.

With fungus action, the earth would be pooled high with_____4______.

In fact, certain plants which contain resins that are ____5_______. Specimen of the redwood tree, for instance can still be found ______6________.

You are watching a fungus acting

Resting on the forest floor centuries after having been cut down

Responsible for decomposition of much plant life

Fungus must look elsewhere for an energy supply

Cannot produce their own store of energy

The dead plant life of past centuries

At some point in their cycle either to animal or to fungi

Fungus is vastly different from other plants

Toxic to fungi will last indefinitely.

One large passage-6marks.

I answer all question from passage in guess becos i have no time to read whole passage care fully.

QUANTITATIVE: 38 Q-40 M

ALL CAME FROM PREVIOUS YR QUESTION. U SHOULD KEEP ON UR MEMORY THE ANSWER OF EACH QUESTION .

THERE IS 3 Q FROM VENN DIAGRAM & 3 FROM PIE CHART.

1. Two pencils costs 8 cents, then 5 pencils cost how much

Sol: 2 pencils è 8 cents => 1 pencil è 4 cents

Therefore 5 pencils cost = 5 * 4 = 20 cents

2. A work is done by two people in 24 min. one of them can do this work a lonely in 40 min. how much time required to do the same work for the second person.

Sol: (A+B) can do the work in = 1/24 min.

A alone can do the same work in = 1/40 min.

B alone can do the same work in = (A+B)’s – A’s = 1/24 – 1/40 = 1/60

Therefore, b can do the same work in = 60 min

3.A car is filled with four and half gallons of oil for full round trip. Fuel is taken 1/4 gallon more in going than coming. What is the fuel consumed in coming up?

Sol Before the trip, car is filled with = 4 ½ gallon of oil

Let ‘X’ be the quantity of fuel consumed for the trip in one direction

The fuel consumed while going = X + ¼

The fuel consumed while coming = X

Therefore, the fuel consumed for the trip = (X + ¼) + X = 4 ½

ð 2X + ¼ = 4 ½ => 2X = 4 ½ – ¼ => 2X = 4 ¼ => X= 2. approx

Therefore the fuel consumed while coming = 2 gallon

4. Low temperature at the night in a city is 1/3 more than 1/2 high as higher temperature in a day. Sum of the low temperature and highest temp. is 100 degrees. Then what is the low temp?

Sol: 40 deg.

5. A person, who decided to go to weekend trip should not exceed 8 hours driving in a day. Average speed of forward journey is 40 m/h. Due to traffic in Sundays, the return journey average speed is 30 m/h. How far he can select a picnic spot?

a) 120 miles

b) Between 120 and 140 miles

c) 160 miles

Answer: 120 miles

6. A person was fined for exceeding the speed limit by 10mph. Another person was also fined for exceeding the same speed limit by twice the same. If the second person was traveling at a speed of 35 mph, find the speed limit.

Sol: Let ‘x’ be the speed limit

Person ‘A’ was fined for exceeding the speed limit by = 10mph

Person ‘B’ was fined for exceeding the speed limit by = twice of ‘A’

= 2*10mph=20mph given that the second person was traveling at the speed of 35mph => 35mph – 20mph = 15mph

Therefore the speed limit is =15 mph

7.A bus started from bus stand at 8.00am, and after 30 minutes staying at destination, it returned back to the bus stand. The destination is 27 miles from the bus stand. The speed of the bus is 18mph. In return journey bus travels with 50% fast speed. At what time it returns to the bus stand?
