This question involves finding A's age using the given relationships between the ages of three people.
We know C = 10 and B is twice C's age.
We know A is 2 years older than B.
Check: C = 10, B = 2 × 10 = 20, A = 20 + 2 = 22 ✓
A's age is 22 years, making the correct answer B) 22.
This question tests your ability to identify the pattern in a sequence of letters.
Convert each letter to its numerical position where A=1, B=2, C=3, and so on.
Calculate the difference between consecutive numbers in the sequence.
The differences increase by 1 each time (2, 3, 4, 5...), so the next difference should be 6.
The next letter in the sequence is U, making the correct answer (B).
This question tests logical deduction using set theory and Venn diagrams to determine if a conclusion necessarily follows from given statements.
We have three sets: Pens, Books, and Tables. The first statement "Some pens are books" means there is an intersection between the Pens set and Books set.
The statement "All books are tables" means every element in the Books set is also in the Tables set, so Books is a subset of Tables.
Since some pens are books (Step 1) AND all books are tables (Step 2), any pen that is a book must also be a table. Therefore, some pens must be tables.
**The conclusion "Some pens are tables" is logically True because any pen belonging to the Books set must also belong to the Tables set, given that all books
This question asks you to count all possible squares of different sizes that can be formed in a 3×3 grid.
In a 3×3 grid, the smallest squares are individual cells.
Larger squares formed by combining four cells in a 2×2 pattern can fit in multiple positions.
The largest possible square is the entire grid itself.
Total squares = 1×1 squares + 2×2 squares + 3×3 squares
The total number of squares in a 3×3 grid is 14.
This question tests logical reasoning through categorical statements and syllogisms.
We have two premises: (1) All roses are flowers, and (2) Some flowers fade.
Since only "some" flowers fade (not all), we cannot conclude that all roses fade. However, roses ARE flowers, so roses could potentially be part of the group that fades.
- (A) "All roses fade" — Too strong; we only know some flowers fade, not all
- (C) "No roses fade" — Contradicts the fact that some flowers fade
- (D) "Roses never fade" — Same as (C); impossible to conclude
**The correct answer is (B) Some roses may fade, because while
This question tests pattern recognition by finding the cipher rule that transforms letters in a word.
Each letter shifts by a consistent number of positions in the alphabet.
Each letter in DOOR shifts forward by 1 position in the alphabet.
Combining all shifted letters in sequence.
The answer is (A) EPPS, as each letter in DOOR shifts forward by exactly one position in the alphabet.
This question tests the ability to arrange people in order based on comparative height statements.
We have four people: A, B, C, and D with the following comparisons.
Ordering them in descending order of height based on the chain of inequalities.
The person at the end of the descending chain is the shortest.
The shortest person is D, so the correct answer is (D).
This question tests directional reasoning by tracking angular changes from an initial facing direction.
You begin facing North.
Turning right (clockwise) from North rotates you 90° clockwise.
Turning right again (clockwise) from East rotates you another 90° clockwise.
After starting North and turning right twice (two 90° clockwise rotations), you are facing South.
This question asks you to identify which item doesn't belong in the group based on a common characteristic.
All items need to be classified into food categories.
Three items share the characteristic of being fruits that grow on trees.
Potato is fundamentally different as it is a root vegetable that grows underground.
Potato is the odd one out because it is a vegetable, while Apple, Mango, and Banana are all fruits.
This question asks you to identify the pattern in the sequence and find the next number.
Calculate the first differences between each pair of adjacent numbers.
The first differences form their own sequence: 3, 5, 7, 9.
The next difference should be 9 + 2 = 11, so add this to the last term.
The next number in the series is 38, making the answer (B).
