DSSSB PGT Mathematics Mock Test - 7 - Question 4

If BANGALORE is written as CZOFBKPQF, how will CALCUTTA be written?

Detailed Solution for DSSSB PGT Mathematics Mock Test - 7 - Question 4

B + 1 = C
A - 1 = Z
N + 1 = O
G - 1 = F
A + 1 = B
L - 1 = K
O + 1 = P
R - 1 = Q
E + 1 = F
BANGALORE → CZOFBKPQF

Similarly,
C +1 = D
A - 1 = Z
L + 1 = M
C - 1 = B
U + 1 = V
T - 1 = S
T + 1 = U
A - 1 = Z
CALCUTTA → DZMBVSUZ

DSSSB PGT Mathematics Mock Test - 7 - Question 5

By solving the inequality 6x - 7 > 5, the answer will be

Detailed Solution for DSSSB PGT Mathematics Mock Test - 7 - Question 5

To solve the inequality 6x - 7 > 5, we need to isolate x on one side of the inequality sign. Here are the steps:
1. Add 7 to both sides of the inequality:
6x - 7 + 7 > 5 + 7
6x > 12
2. Divide both sides of the inequality by 6:
6x/6 > 12/6
x > 2
Therefore, the solution to the inequality 6x - 7 > 5 is x > 2. This means that x is greater than 2. Therefore, the correct answer to the question is D: x > 2

DSSSB PGT Mathematics Mock Test - 7 - Question 6

Who among the following was the mother of Prabhavati Gupta?

Detailed Solution for DSSSB PGT Mathematics Mock Test - 7 - Question 6

DSSSB PGT Mathematics Mock Test - 7 - Question 10

Direction: When I logged in to Facebook this week,i was greeted with updates from such friends as Mareah Carey, Natalie portman and
Ryan Gosling, right? Except that when i clicked through. It was clear that these posts were from my same, lame no-name
friends who were simply jumping on the latest Facebook bandwagon. Yes, it is (or was as these things don’t exactly have strict
expiration dates) Celebrity doppelganger week on Facebook , during which people replace their profile picture with the celeb
they think they look most like them.
This is the operative word here. I love my friends, but trust me-it’s a motley crew that little resembles anyone casting directors would want to put in a feature film. But more disturbing than the creative liberties they took in choosing their twins is that, this is just the latest example of how my friends-and hundreds of thousands of people around the world-are susceptible to face book groupthink. These are grass-roots names that spread virally throughout the site, making them difficult to trace back to an origin with any certainty. The Huffington post published what appeared to be the transcript of an interview with Bob Patel, and IT worker who says his resemblance to Tom selleck prompted the start of Doppelganger Week. But the claim (and the transcript itself) is dubious-the article is even tagged as “satire,” but that hasn’t stopped blogs and news organizations from citing Patel as the instigator.

Q. Which of the following best represents the theme of the passage ?

Detailed Solution for DSSSB PGT Mathematics Mock Test - 7 - Question 10

Option (a) and (d) are not mentioned anywhere in the passage, Option (c) is actually correct but not the central idea. Option (b) is the best option.

DSSSB PGT Mathematics Mock Test - 7 - Question 11

Direction: Read the following passage carefully and answer the questions. Your answer to these questions should be based on passage only.

We are very disappointed with the change in the date. It was a law enacted and approved by Parliament, which was supposed to benefit citizens. The delay in the deadline for digitization is more of a knee jerk reaction by the Ministry of Information and Broadcasting to its inability to resolve crucial differences between stakeholders. While broadcasters and DTH operators want the government to fast-track the process, local cable operators have asked for a further extension of introduction of the technology is done in a manner that creates a level playing field for all the stakeholders. A government mandated imposition of technology, in this instance, will benefit only a privileged few and deprive a large section of the population of the benefits of inexpensive cable TV.

Q. What was the impact of introduction of new technology in TV world?

Detailed Solution for DSSSB PGT Mathematics Mock Test - 7 - Question 11

The impact of introduction of new technology in TV world will give the benefit only to rich people and deprive the poor people. Other (a), (b) and (d) are not appropriate .

DSSSB PGT Mathematics Mock Test - 7 - Question 12

In covering a distance of 30 km, Arun takes 2 hours more than Anil. If Arun doubles his speed, then he would take 1 hour less than Anil. What is Arun's speed?

Detailed Solution for DSSSB PGT Mathematics Mock Test - 7 - Question 12

Let Anil takes x hrs.
⇒ Arun takes x+2

If Arun doubles the speed, he will take x-1 hrs
⇒ He needs 3 hours less.
∵ Double speed means half time.
∴ Half of the time required by Arun to cover 30 km = 3 hours

⇒ Time required by Arun to cover 30 km = 6 hour
Thus, Arun's speed = 30/6 = 5 km/h

DSSSB PGT Mathematics Mock Test - 7 - Question 17

Tea worth Rs. 126 per kg and Rs. 135 per kg are mixed with a third variety of tea in the ratio 1 : 1 : 2. If the mixture is worth Rs. 153 per kg, what is the price of the third variety per kg ?

Detailed Solution for DSSSB PGT Mathematics Mock Test - 7 - Question 17

► Since first and second varieties are mixed in equal proportions.So, their average price = Rs.
= Rs. 130.50

► So, the mixture is formed by mixing two varieties, one at Rs. 130.50 per kg and the other at say, Rs. x per kg in the ratio 2 : 2, i.e., 1 : 1. We have to find x.

By the rule of alligation, we have:

DSSSB PGT Mathematics Mock Test - 7 - Question 18

Three taps A, B and C can fill a tank in 12, 15 and 20 hours respectively. if A is open all the time and B and C are open for one hour each alternately, the tank will be full in:
A. 
B. 6 hours 

C. 
D. 7 hours

Detailed Solution for DSSSB PGT Mathematics Mock Test - 7 - Question 18

(A + B)'s 1 hour's work =  = 9/60 = 3/20.
(A+C)'s hour's work =   = 8/60 = 2/15.
Part filled in 2 hrs = 

Part filled in 6 hrs = 
Remaining part = 
Now, it is the turn of A and B and 3/20 part is filled by A and B in 1 hour.
∴ Total time taken to fill the tank = (6+1) hrs = 7 hrs

DSSSB PGT Mathematics Mock Test - 7 - Question 26

The distance of the point (2,3,5) from the line  is

Detailed Solution for DSSSB PGT Mathematics Mock Test - 7 - Question 26

The eqution of line is given as, 

The coordinate of point B on the given line are,

B (-3λ- 2, 4λ+ 2, λ -2)

and the given coordinate of point A  is  ( 2, 3, 7). 

AB is perpendicular to the line, 

We know that, If two lines are Perpendicular, then  a1a2+b1b2+c1c2 = 0,

⇒ (-3λ- 4 ) × (-3) + (4λ-1 )× 4 + (λ + 5 )× 1 = 0

⇒ 26λ + 13 = 0

DSSSB PGT Mathematics Mock Test - 7 - Question 28

Find the sum of all numbers divisible by 6 in between 100 to 400.

Detailed Solution for DSSSB PGT Mathematics Mock Test - 7 - Question 28

Given,

1st term = a = 102

(Which is the 1st term greater than 100 that is divisible by 6.) 

The last term less than 400, Which is divisible by 6 is 396. 

Terms in the AP; 102, 108, 114 … 396

Now

First term = a = 102

Common difference = d = 108 - 102 = 6

nth term = last term (l) = 396

As we know, nth term of AP = an

= a + (n – 1) d

⇒ 396 = 102 + (n - 1) × 6

⇒ 294 = (n - 1) × 6

⇒ (n - 1) = 49

∴ n = 50

Sum =

DSSSB PGT Mathematics Mock Test - 7 - Question 30

Consider the following statements:

1. If in a triangle ABC, A = 2B and b = c, then it must be an obtuse-angled triangle.

2. There exists no triangle ABC with A = 40o, B = 65o and

Which of the above statements is/are correct?

Detailed Solution for DSSSB PGT Mathematics Mock Test - 7 - Question 30

We have, in ΔABC.

A= 2B and b = c

⇒ Angles opposite to equal sides are equal.

∴ ∠C = ∠B

Also, A= 2B = 2C

Thus, it shows that ΔABC is not an obtuse angle triangle. 

So, statement 1 is incorrect.
