DSSSB TGT Social Science Mock Test - 8 - Question 13

Twenty women can do a work in sixteen days. Sixteen men can complete the same work in fifteen days. What is the ratio between the capacity of a man and a woman?

Detailed Solution for DSSSB TGT Social Science Mock Test - 8 - Question 13

(20 x 16) women can complete the work in 1 day.
∴ 1 woman's 1 day's work =1/320
(16 x 15) men can complete the work in 1 day.
∴ 1 man's 1 day's work = 1/240
So, required ratio = 1/240 : 1/320
⇒ 1/3 :1/4
⇒ 4 : 3 (cross multiplied)

DSSSB TGT Social Science Mock Test - 8 - Question 14

A and B can do a work in 8 days, B and C can do the same work in 12 days. A, B and C together can finish it in 6 days. A and C together will do it in :

Detailed Solution for DSSSB TGT Social Science Mock Test - 8 - Question 14

(A + B + C)'s 1 day's work = 1/6
(A + B)'s 1 day's work = 1/8    
(B + C)'s 1 day's work = 1/12    
Therefore (A + C)'s 1 day's work    
⇒ (2 x 1/6) - (1/8 + 1/12)
⇒ (1/3 - 5/24)
⇒ 3/24
⇒ 1/8
So, A and C together will do the work in 8 days.

DSSSB TGT Social Science Mock Test - 8 - Question 15

A grocer has a sale of Rs. 6435, Rs. 6927, Rs. 6855, Rs. 7230 and Rs. 6562 for 5 consecutive months. How much sale must he have in the sixth month so that he gets an average sale of Rs. 6500?

Detailed Solution for DSSSB TGT Social Science Mock Test - 8 - Question 15

Total sale for 5 months = Rs. (6435 + 6927 + 6855 + 7230 + 6562) = Rs. 34009.

 Required sale = Rs. [ (6500 x 6) - 34009 ]

   = Rs. (39000 - 34009)

   = Rs. 4991.

DSSSB TGT Social Science Mock Test - 8 - Question 16

The average weight of A, B and C is 45 kg. If the average weight of A and B be 40 kg and that of B and C be 43 kg, what is the weight of B?

Detailed Solution for DSSSB TGT Social Science Mock Test - 8 - Question 16

Let A, B, C represent their respective weights. Then, we have:

A + B + C = (45 x 3) = 135 .... (i)

A + B = (40 x 2) = 80 .... (ii)

B + C = (43 x 2) = 86 ....(iii)

Adding (ii) and (iii), we get: A + 2B + C = 166 .... (iv)

Subtracting (i) from (iv), we get : B = 31.

 B's weight = 31 kg.

DSSSB TGT Social Science Mock Test - 8 - Question 17

What is the simple interest for 9 years on a sum of Rs. 800 if the rate of interest for the first 4 years is 8% per annum and for the last 4 years is 6% per annum?

Detailed Solution for DSSSB TGT Social Science Mock Test - 8 - Question 17

8% of 800 for 4 years + 6% of 800 for 4 years = 64 x 4 + 48 x 4 = 256 + 192 = 448. However, we do not know the rate of interest applicable in the 5 th year and hence cannot determine the exact simple interest for 9 years.

DSSSB TGT Social Science Mock Test - 8 - Question 18

Detailed Solution for DSSSB TGT Social Science Mock Test - 8 - Question 20

30% of 200 = 60
People traveled by Train B on Friday = 260
260 : 320 = 13 : 16

Detailed Solution for DSSSB TGT Social Science Mock Test - 8 - Question 25

Answer – a) 5/8 Explanation : let total employees are 100 males = 40 and females = 60 (45 women earns more than 20000) total 60 employee earns more than 20000 per month, so number of males earns more than 20000 is 15 so fraction = 25/40 = 5/8

DSSSB TGT Social Science Mock Test - 8 - Question 27

The cost of a diamond varies directly as the square of its weight. Once, this diamond broke into four pieces with weights in the ratio 1 : 2 : 3 : 4. When the pieces were sold, the merchant got Rs. 70,000 less. Find the original price of the diamond.

Detailed Solution for DSSSB TGT Social Science Mock Test - 8 - Question 27

Cost ∝ Weight2
Let original weight = 10x
Then, original cost = 100x2k (where k is proportionality constant)
After breakage weight = 1x + 2x + 3x + 4x
After breakage cost = kx2(1 + 4 + 9 + 16) = 30x2k
Now, (100 - 30)x2k = 70,000
Or, 70x2k = 70,000
Or, x2k = 1,000
Hence, original cost = 100x2k
= 100 × 1,000 = Rs. 1,00,000

DSSSB TGT Social Science Mock Test - 8 - Question 28

A sum of Rs. 735 was divided among A, B and C. If each of them had received Rs. 25 less, then their shares would have been in the ratio 1 : 3 : 2. What is the money received by C?

Detailed Solution for DSSSB TGT Social Science Mock Test - 8 - Question 28

Suppose after the reduction of Rs. 25, the shares of A, B and C are x, 3x and 2x, respectively.
Total money = 6x (after reduction)
Initially, share (A) + share (B) + share (C) = 735 … (1)
After reduction,
share (A) - 25 + share (B) - 25 + share (C) - 25 = 6x
⇒ share (A) + share (B) + share (C) - 75 = 6x ... (2)
From (1) and (2), we get
⇒ 735 - 75 = 6x
⇒ x = 660/6 = 110
Now, after deduction, C has, 2x = 2 × 110 = Rs. 220.
Before deduction, C had, 220 + 25 = Rs. 245

DSSSB TGT Social Science Mock Test - 8 - Question 29
