2) Answer (B)
3) Answer (B)
4) Answer (D)
5) Answer (D)
6) Answer (A)
7) Answer (B)
8) Answer (D)
9) Answer (D)
10) Answer (C)
11) Answer (D)
We can draw the diagram as shown in the figure below.
Let ‘U’ be the intersecting point of medians PS and RT. Let ‘3x’ and ‘3y’ be the lengths of medians PS and RT respectively.
Given that the medians intersect at a right-angle, $\angle$ PUR = $\angle$ RUS = $\angle$ SUT = $\angle$ TUP = 90°
In right-angle triangle PUR,
$PR^2 = PU^2+UR^2$
$PR^2 = (2x)^2+(2y)^2$
$PR^2 = 4x^2+4y^2$ … (1)
Similarly, in right-angle triangle PUT,
$PT^2 = PU^2+UT^2$
$(\dfrac{PQ}{2})^2 = (2x)^2+(y)^2$
$PQ^2 = 16x^2+4y^2$ (2)
In right-angle triangle RUS,
$RQ^2 = 4x^2+16y^2$ (3)
By adding (1), (2) and (3), we get
$PQ^2+QR^2+RP^2=24(x^2+y^2)$
We are given that $(3x)^2+(3y)^2 = 81$ => $x^2+y^2$ = 9
Hence, $PQ^2+QR^2+RP^2=24*9=216$
We know that three times the sum of the squares of the sides of a triangle is equal to four times the sum of the squares of the medians of the triangle. Therefore,
$3(PQ^2+QR^2+RP^2)=4(PS^2+RT^2+QV^2)$
$PS^2+RT^2+QV^2=\dfrac{3*216}{4}$
$81+QV^2=162$
$QV=9$ cm
Hence, option D is the correct answer.
12) Answer (D)
Discriminant = $b^2-4ac = (-4)^2-4(3)(-4) = 16+48 = 64 > 0$
So roots are real and unequal.
The product of p and q is $-4/3$, hence one of them is greater than 0 and the other is less than 0.
So the answer is option D.
13) Answer (C)
From the given sentence, we can infer that the price of the vegetables has been on continuous rise for the last one year. Options A and B fail to capture the continuity of the process. Option D states that the prices of the vegetables were rising last year. But it fails to capture the point that the price is still on the rise.
Therefore, option C is the right answer.
14) Answer (C)
Option C consists of two independent clauses which cannot be joined with the comma. There are three things one can do with independent clauses. One can make them two separate sentences using period, join them using a semicolon, or join them with a comma and coordinating conjunction. Hence, option C is grammatically incorrect.
All other options are correct.
Hence, option C is the right answer.
15) Answer (B)
Correct usage is ‘comply with’, hence option a and c are incorrect.
Also, ‘abide by’ is the correct usage. Hence option d which uses ‘abide with’ is incorrect and can be eliminated.
Usage of ‘follow by’ is incorrect. Hence option B which uses ‘abide by’ is correct.
