Rs. 6999.20
C.
Rs. 6654
D.
Rs. 7000

Your Answer: Option (Not Answered)

Rs. 9800 are invested partly in 9% stock at 75 and 10% stock at 80 to have equal amount of incomes. The investment in 9% stock is:

A.
Rs. 4800
B.
Rs. 5000
C.
Rs. 5400

Let the investment in 9% stock be Rs. x.

Then, investment in 10% stock = Rs. (9800 - x).

9 x x = 10 x (9800 - x)
75 80

3x = 9800 - x
25 8

24x = 9800 x 25 - 25x

49x = 9800 x 25

x = 5000.

Income in 1st case = Rs. 11 x 143 x 117 = Rs. 1287.
143

Income in 2nd case = Rs. 39 x 143 x 117 = Rs. 1394.25
4 x 117

Clearly, 9 3 % stock at 117 is better.

B.
214344
C.
214434

In a race of 200 m, A can beat B by 31 m and C by 18 m. In a race of 350 m, C will beat B by:

A.
22.75 m
B.
25 m
C.
19.5 m
D.
7 4 m
7

Your Answer: Option (Not Answered)

Correct Answer: Option B

Explanation:

A : B = 200 : 169.

A : C = 200 : 182.

C = C x A = 182 x 200 = 182 : 169.
B A B 200 169

When C covers 182 m, B covers 169 m.

When C covers 350 m, B covers 169 x 350 m = 325 m.
182

Therefore, C beats B by (350 - 325) m = 25 m.

16
B.
34
C.
105
D.
424
E.
2124

Your Answer: Option (Not Answered)

Correct Answer: Option E

Explanation:

2nd term = (1st term) x 1 + 1 = 15 x 1 + 1 = 16.

3rd term = (2nd term) x 2 + 2 = 16 x 2 + 2 = 34.

4th term = (3th term) x 3 + 3 = 34 x 3 + 3 = 105.

5th term = (4th term) x 4 + 4 = 105 x 4 + 4 = 424

6th term = (5th term) x 5 + 5 = 424 x 5 + 5 = 2125

6th term should 2125 instead of 2124.

Your Answer: Option (Not Answered)

Correct Answer: Option E

Explanation:

Let us name Ravi, Gagan and Nitin by R, G and N respectively.

 I. R : G : N = 2 : 4 : 7.

II. N = 8750..

From I and II, we get:

When N = 7, then G = 4.

When N = 8750, then G = 4 x 8750 = 5000.
7

Thus, both I and II are needed to get the answer.

Correct answer is (E).

A.
Any two of the three
B.
I and II only
C.
II and III only
D.
I and III only
E.
None of these

Your Answer: Option (Not Answered)

Correct Answer: Option A

Explanation:

  I. (10 x 6) men can complete the work in 1 day.

      1 man's 1 day's work = 1
60


 II. 10 x 24 men + 10 x 24 women can complete the work in 1 day.
7 7

      240 men's 1 day work + 240 women's 1 day work = 1.
7 7

      240 x 1 + 240 women's 1 day's work = 1.
7 60 7

      240 women's 1 day's work = 1 - 4 = 3
7 7 7

      10 women's 1 day's work = 3 x 7 x 10 = 1
7 240 8

      So, 10 women can finish the work in 8 days.


III. (10 men's work for 3 days) + (10 women's work for 4 days) = 1

      (10 x 3) men's 1 day's work + (10 x 4) women's 1 day's work = 1

      30 men's 1 day's work + 40 women's 1 day's work = 1


      Thus, I and III will give us the answer.

      And, II and III will give us the answer.

      Correct answer is (A).
