An architect designs and creates a building; in the same way, a sculptor creates a statue. The chisel is merely the tool, not the creation.

2) Find the odd one out:

  1. 121
  2. 169
  3. 225
  4. 252
Show Answer
Answer: d
Explanation
121 = 11², 169 = 13² and 225 = 15² are all perfect squares, whereas 252 is not a perfect square, so it is the odd one out.

Show Answer
Answer: a
Explanation
Every letter of FLOWER is moved one step backward (F→E, L→K, O→N, W→V, E→D, R→Q). Applying the same rule to GARDEN gives FYQCDM (G→F, A→Z, R→Q, D→C, E→D, N→M).

  4. 20 km
Show Answer

  1. 15
  2. 17
  3. 19
  4. 21
Show Answer
Answer: b
Explanation
Substituting the symbols: 16 × 8 + 4 − 2 ÷ 3 becomes 16 + 8 ÷ 4 × 2 − 3. By BODMAS: 8 ÷ 4 = 2, then 2 × 2 = 4, so 16 + 4 − 3 = 17.

10) Select the number that will replace the question mark (?):
2, 6, 12, 20, 30, 42, ?

  1. 52

Answer: c
Explanation
The terms are products of consecutive integers: 1×2=2, 2×3=6, 3×4=12, 4×5=20, 5×6=30, 6×7=42. The next term is 7×8 = 56.

11) Statements:
1. All books are pens.
2. All pens are markers.
Conclusions:
I. All books are markers.
II. Some markers are pens.

  1. Only conclusion I follows
  2. Only conclusion II follows
  3. Both conclusions follow
  4. Neither follows
Show Answer
Answer: c
Explanation
Since all books are pens and all pens are markers, all books must also be markers (conclusion I follows). Also, because every pen is a marker, some markers are definitely pens (conclusion II follows). Hence both conclusions follow.

  1. 26
  2. 28
  3. 30

AZ, BY, CX, DW, ?

  1. EV
  2. FU
