Answers & Solutions:

1) Answer (E)

From statement 1 or statement 2 alone, we cannot determine the position of Bhavna.
Using both the statements,
_ _ _ _ _ _ Sheetal _ Sandeep _ Anita _ _ Bhavna …
So, Bhavna’s position can be determined using both the statements together.

2) Answer (C)

From statement 1 alone: R A N G E is the only possibility
From statement 2 alone: R/E A/G N G/A E/R is the possibility. So, the middle letter can be determined.
So, the question can be answered by using either statement alone.

3) Answer (B)

From statement 1, the positions are as follows:

From statement 2, the positions are as follows:

So, the question can be answered by using statement 2 alone, but not by using statement 1 alone.

4) Answer  (B)

Downstream = boat + stream = $\frac{12}{2}$ + stream = 6 km/hr
Upstream =boat – stream = $\frac{12}{4}$ – stream  = 3 km/hr
Solving the above equations we get boat = 4.5 km/hr and stream = 6 – 4.5 = 1.5
Speed of the stream = $\frac{1}{3}$rd of that of the boat in still river = 1.5

5) Answer (B)

Length of the train = 240 m
Time taken to cross the pole = 24 seconds
Speed = $\frac{240}{24}$ = 10 m/s

6) Answer (E)

Let x be the average age of students
Let y be the teacher’s age
$\frac{11x + y}{12}$ = 14
$\frac{11x + y}{12}$ = x + 3
Solving the above equations we get x = 11
y = 47

7) Answer (C)

SI in 1 year = 600

for two years = 1200

Sum = 10 x 1200 = 12000

600 = 12000*r*1/100

r = 5%

Amount returned in two years = 12000(1 + $\frac{5}{100}$)2 = 13230

8) Answer (D)

Length of the hypotenuse = 5 cm
Other two sides = 4cm ,3 cm (pythaogrean triples)
Area = $\frac{1}{2}$ x base x height = $\frac{1}{2}$ x 3 x 4 = 6cm2
