Tick ( ) the correct option.

1. Using the digits 1, 2, 3, and 4, form the largest 4. A 3-digit number is formed using three
and smallest four-digit even numbers. What is different digits, and the digits are reversed to
create another 3-digit number. The difference
the sum of the digits of the difference between
between these two numbers always divisible
these two numbers? (Analytical Thinking) by: (Analytical Thinking)

(a) 13 (b) 10 (a) 11 (b) 33

(c) 99 (d) All of these
(c) 18 (d) 12
5. Replace the letters with suitable digits.
2. A six-digit number has the same number of
(Abstract Thinking)
prime and non-prime digits. Which of the B 4

following could possibly be the sum of the + A A
digits of this number? (Critical Thinking) 1 1 0
(a) A = 3, B = 7
(a) 18 (b) 22
(b) A = 6, B = 4
(c) 27 (d) All of these
(c) A = 5, B = 6
3. A computer generates triangles where the
base and height follow a series given below. If (d) A = 4, B = 6
the pattern continues, what will be the area of 6. Find the values of O, U, T, and G in the given
the next triangle the computer should draw? sum: (Abstract Thinking)
T O
2 × 1, 3 × 2, 6 × 5, 30 × 11, ...? (Pattern Recognition) + G O

(a) 6765 sq. units O U T
(a) O = 2, U = 0, T = 1, G = 5
(b) 330 sq. units
(b) O = 1, U = 0, T = 2, G = 8
(c) 9890 sq. units
(c) O = 0, U = 2, T = 5, G = 3
(d) 4935 sq. units.
(d) O = 1, U = 3, T = 5, G = 1
