1.

An observer 1.6 m tall is 203 away from a tower. The angle of elevation from his eye to the top of the tower is 30°. The height of the tower is:

A.
21.6 m
B.
23.2 m
C.
24.72 m
D.
None of these

Your Answer: Option (Not Answered)

Correct Answer: Option A

Explanation:

Let AB be the observer and CD be the tower.

Draw BE CD.

Then, CE = AB = 1.6 m,

      BE = AC = 203 m.

DE = tan 30° = 1
BE 3

DE = 203 m = 20 m.
3

CD = CE + DE = (1.6 + 20) m = 21.6 m.

What is Ravi's present age?

I. 

The present age of Ravi is half of that of his father.

II. 

After 5 years, the ratio of Ravi's age to that of his father's age will be 6 : 11.

 III. 

Ravi is 5 years younger than his brother.

D.
All I, II and III
E.
Even with all the three statements answer cannot be determined.

Your Answer: Option (Not Answered)

Correct Answer: Option A

  I. Let Ravi's present age be x years. Then, his father's present age = 2x years.

 II. After 5 years, Ravi's age = 6
Father's age 11

III. Ravi is younger than his brother.

From I and II, we get x + 5 = 6 .   This gives x, the answer.
2x + 5 11

Thus, I and II together give the answer. Clearly, III is redundant.

Your Answer: Option (Not Answered)

Correct Answer: Option A

Explanation:

Total number of balls = (2 + 3 + 2) = 7.

Let S be the sample space.

Then, n(S) = Number of ways of drawing 2 balls out of 7
= 7C2 `
= (7 x 6)
(2 x 1)
= 21.

Let E = Event of drawing 2 balls, none of which is blue.

n(E) = Number of ways of drawing 2 balls out of (2 + 3) balls.
= 5C2
= (5 x 4)
(2 x 1)
= 10.

P(E) = n(E) = 10 .
n(S) 21

In a regular week, there are 5 working days and for each day, the working hours are 8. A man gets Rs. 2.40 per hour for regular work and Rs. 3.20 per hours for overtime. If he earns Rs. 432 in 4 weeks, then how many hours does he work for ?

A.
160
B.
175
C.
180
D.
195

Your Answer: Option (Not Answered)

Correct Answer: Option B

Explanation:

Suppose the man works overtime for x hours.

Now, working hours in 4 weeks = (5 x 8 x 4) = 160.

160 x 2.40 + x x 3.20 = 432

3.20x = 432 - 384 = 48

x = 15.

Hence, total hours of work = (160 + 15) = 175.

4 4 %
7
B.

Selling Price (S.P.) = Rs. 5800.

Gain = (S.P.) - (C.P.) = Rs.(5800 - 5500) = Rs. 300.

Gain % = 300 x 100 % = 5 5 %
5500 11

9n x 3n - 1

A.
1
B.
2
C.
9
D.
3n

Your Answer: Option (Not Answered)

Correct Answer: Option C

Explanation:

Given Expression
= (243)(n/5) x 32n + 1

9n x 3n - 1

= (35)(n/5) x 32n + 1

(32)n x 3n - 1
