Answer : Option AExplaination / Solution:
Given that
Q3.Which of the following is CORRECT with respect to grammar and
usage? Mount Everest is ____________.
Answer : Option AExplaination / Solution:
The sentence is stating the highest peak in the world. Since
it is a specific thing, we need to use the definite article ‘the’ before it.
Also the sentence is using the superlative degree and so we say ‘the
highest peak in the world’ making option 1 the correct answer. There
cannot be many highest peaks in the world and so options 3 and 4
are incorrect.
Q4.Despite the new medicine’s ______________ in treating diabetes, it is not
_____________widely.
Answer : Option AExplaination / Solution:
The sentence is looking for a contrast as it is joined by the
conjunction ‘despite’. The best pair of words that can fit the context
of the sentence is ‘effectiveness…prescribed’. Though the medicine is
‘effective’ in treating diabetes, it is not being ‘prescribed’ widely. A
new medicine cannot have a ‘prescription’ or ‘availability’ for treating
a disease. ‘Proscribed’ means forbidden by law. In case we use
‘acceptance…proscribed’ the sentence will not make any sense
because it will mean that though the medicine is accepted widely, it is
not forbidden by law.
Q5.In a huge pile of apples and oranges, both ripe and unripe mixed
together, 15% are unripe fruits. Of the unripe fruits, 45% are apples.
Of the ripe ones, 66% are oranges. If the pile contains a total of
5692000 fruits, how many of them are apples?
Answer : Option AExplaination / Solution:
Let T = total no of fruits = 5692000
Q6.Michael lives 10 km away from where I live. Ahmed lives 5 km away
and Susan lives 7 km away from where I live. Arun is farther away
than Ahmed but closer than Susan from where I live. From the
information provided here, what is one possible distance (in km) at
which I live from Arun’s place?
Answer : Option CExplaination / Solution:
In question it is given that Ahmed is 5Km away and Susan is 7Km
away from where I live. Further it is given that Arun is farther away
than Ahmed from where I live and not as far as Susan. That means
Arun must be living at distance more than 5Km but less than 7Km
from my house which is according to given options can be 6.02Km.
Note: Information about Michal is unnecessary and just given to
confuse.
Q7.A person moving through a tuberculosis prone zone has a 50%
probability of becoming infected. However, only 30% of infected
people develop the disease. What percentage of people moving
through a tuberculosis prone zone remains infected but does not
show symptoms of disease?
Answer : Option CExplaination / Solution:
Percentage probability of being infected = P(A) = 50%
Percentage probability of infected person developing disease is having
system, = P(B) = 30%
∴ Percentage probability of infected person not showing symptoms = = 70%
Percentage probability of person moving though a TB prone zone
remaining infected but not showing symptoms = P(A).= 50/100 × 70/100 = 35%
Q8.Leela is older than her cousin Pavithra. Pavithra’s brother Shiva is

Q10.P, Q, R and S are working on a project. Q can finish the task in
25 days, working alone for 12 hours a day. R can finish the task in 50
days, working alone for 12 hours per day. Q worked 12 hours a day
but took sick leave in the beginning for two days. R worked 18 hours
a day on all days. What is the ratio of work done by Q and R after 7
days from the start of the project?
Answer : Option CExplaination / Solution:
After 7 days from start of project:
Q took sick leave on first 2 days
∴ Man hours by Q = 5×12
∴ Work done by Q = 5 × 12 × 1/(25×12) = 1/5
Man hours by R = 7×18
∴ Work done by R = 1/(50×12) × 7 × 18 = 21/100
∴ Ratio of work done by Q to work done by R = 1/5:21/100 = 100/(5×21) = 20/21
