Correct Answer: If the data even in both statements I and II together are not sufficient to answer the question.
Explanation:
Data in both statements I and II together are not sufficient to answer the question. Hence, required answer is option D .
Correct Answer: If the data in either Statement I alone or in Statement II alone are sufficient to answer the question
Explanation:
From Statement I.
Let the ratio proportion is x.
some of angle of triangle = 180 °
3x + 5x + 4x = 180 °
12x = 180 °
x = 180 ° /12
x = 15 °
Largest angle of triangle
= 5x = 5 x 15
= 75 °
? Larger angle of parallelogram
= 75 ° + 34 °
= 109 °
? Smaller angle of parallelogram
= 180 ° - 109 °
= 71 °
From Statement II,
Let the smaller angle of parallelogram be = x
and the larger angle of parallelogram = x + 38 °
Sum of two opposite angles of a parallelogram = 180 °
x + x + 38 ° = 180 °
? 2x = 180 ° - 38°
? 2x = 142°
? x = 142° / 2
? x = 71 °
Correct Answer:
Explanation:
From Statement I,
Area of square = 576 sq cm
? Side of square = Square root of Square's area
? Side of square = Square root of 576 = 24 cm
and area of rectangle = 600 sq cm
area of rectangle = ( length x breadth ) of rectangle
We cannot find the length of rectangle
From Statement II,
Breadth of rectangle = side of square x 1/2
Breadth of rectangle = 24 x 1/2 = 12 cm
? Length of rectangle = 600/12 = 50 cm
? Ratio = Length of rectangle/ Side of square = 50/24
= 25/12
Correct Answer: If the data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question
Explanation:
From Statement I , given that
4p + 3q + 5r = 60...............(i)
2p = q
? p = q/2 ................(ii)
and 2q = r ....................(iii)
putting the value of p and r in terms of q in Eq. (i),
4 x q/2 + 3q + 5 x 2q = 60
15q = 60
? q = 4
put the value of q in Eq. (ii)
? p = q/2 = 4/2
p = 2;
put the value of q in Eq. (iii)
? r = 2q = 2 x 4
? r = 8
? value of p2 + q + r = (2)2 + 4 + 8 = 16
From Statement II,
3x + 3y + 2z = 34 ..............(a)
and 2x + 5y + 6z = 72 ....(b)
We cannot find the value of p, q and r from Eqs. (a) and (b)
Correct Answer: If the Statement II alone is sufficient to answer the question but the Statement I alone is not sufficient
Explanation:
From Statement I,
Raveena is half as old as Karishma. But we don't know the age of Karishma.
From Statement II,
Age of Raveena = three-fifth of her mother's age
Age of Raveena = Age of her Mother x 3/5
Age of Raveena = 45 x 3/5 = 27 yr
Correct Answer: if the data either in statements I alone or in statement II alone are sufficient to answer the question; and
Explanation:
From I: If all of them face the centre, it means if A sits second to the left of B, then B should sit second to the right of A. But here Amit and Arun are different persons. Hence all of them do not face the centre
From II: Again suppose of them face the centre like KEN. Ali sits third to the left of ken. Now, if Amit sits on the left of Ali obviously ken should be his neighbour. But the statement says otherwise. Hence our assumption is disproved. All of them do not face the centre.
Correct Answer:
Explanation:
In I, Sex of T is not known. In II, Q does not figure. Hence we need both the statements to establish the relationship.
Correct Answer: if the data given in both the statement I and II together are not sufficient to answer the question; and
Explanation:
From I: We don't known whether B is to the west or east of C. In fact, it could be in any other direction.
From II: Obviously A is west of B.
Correct Answer: if the data in both the Statement I and II are not sufficient to answer the question.
Explanation:
From I: Bharat has two siblings but we don't know their sex.
Correct Answer: if the data in both the Statement I and II together are not sufficient to answer the question.
Explanation:
Using Statement I:
a letter ? '71'
Using Statement II:
'in' ? '4'
Using both:
'Greek' ? '5' and 'received ? '3'
Code for 'letter' cannot be found even by using both statements together.
