- If the Statement II alone is sufficient to answer the question but the Statement I alone is not sufficient
ExplanationFrom 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 - 1. In how many year can a simple interest of ?6570 be obtained on an amount of ? 36500?

Correct Answer: If the Statement I alone is sufficient to answer the question but the Statement II alone is jot sufficient
Explanation:
Apply the law of Simple Interest.
Simple Interest ( S.I ) = (P x R x T)/100
where Principal amount = P,
Rate of Interest = R% per year and
Time = T years.
Then
T = (S.I x 100)/P x R
From Statement I,
? T = 6570 x 100/36500 x 6
? T = 6570 x 1/365 x 6
? T = 1095 x 1/365
? T= 1095/365
? T= 3 yr
I statement is enough to answer the question. II statement is not enough alone to answer the question.
Correct Answer:
Explanation:
The total number of student is given in the question.
Number of teachers are less than students, But we cannot tell exact how many teachers are there in school.
Data is insufficient, so we cannot get answer from all two statements.
Correct Answer:
Explanation:
from Statements I and II,
9 - 9 = 0 and 9 + 9 = 18
So, number = 99
Correct Answer: Any two of three
Explanation:
Area of triangle = 1/2 x Base x Height
So, to find the area, the measure of height and base is required which can be obtained by any of the two statement.
Correct Answer: Six
Explanation:
Input Year 39 atake 47 house 94 55
Step I full year 39 stake 47 house 94 55
Step II full 94 year 39 stake 47 house 55
Step III full 94 house year 39 stake 47 55
Step IV full 94 house 55 year 39 stake 47
Step V full 94 house 55 year stake year 39 47
Step VI full 94 house 55 stake 47 year 39
Hence, six step will required to complete the arrangement.
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:
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 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: 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 statement I alone is sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
Explanation:
From I: P > O > N
From II: L > M From I and II, either M or N is the shortest. We can't determine who is shorter between the two of them.
