Part 1: Mensuration (Area & Volume)

Question 1:

The radius of a circular garden is $14\text{ m}$ . What is the cost of leveling the garden at the rate of $10$ per square meter?

A) ₹ $6,160$

B) ₹ $4,400$

C) ₹ $3,080$

D) ₹ $1,540$

Answer: A) ₹6,160

Tip:

First, find the Area ( $\pi r^2$ ).
Area = $(22/7) \times 14 \times 14 = 616\text{ sq.m}$
Cost = $616 \times 10 = ₹6,160$ .

Question 2:

A cuboid has dimensions $10\text{ cm} \times 8\text{ cm} \times 5\text{ cm}$ Find its Total Surface Area (TSA).

A) $400\text{ sq.cm}$

B) $340\text{ sq.cm}$

C) $280\text{ sq.cm}$

D) $170\text{ sq.cm}$

Answer: B) 340 sq.cm

Tip:

Formula:2( $2(lb + bh + hl)$
$2(10 \times 8 + 8 \times 5 + 5 \times 10) = 2(80 + 40 + 50)$
$2(170) = 340\text{ sq.cm}$ .

Part 2: Analytical Reasoning

Question 3: (Number Series)

Find the missing number in the series: $2, 6, 12, 20, 30, \underline{?}$

A) $36$

B) $40$

C) $42$

D) $44$

Answer: C) 42

Tip:

Check the difference between the numbers:

$6 - 2 = 4$
$12 - 6 = 6$
$20 - 12 = 8$
$30 - 20 = 10$
Next difference should be $12$ . So, $30 + 12 = 42$ .

Question 4: (Coding-Decoding)

If 'DRAGON' is coded as 'EGZHPM', how is 'TIGER' coded?

A) UFJFS

B) UHHFS

C) UJFDS

D) SFHDS

Answer: B) UHHFS

Tip:

Look at the pattern:

$D + 1 = E$
$R - 1 = Q$ (Wait, let's re-check the logic: $+1, -1, +1, -1 \dots$
$D(+1) \rightarrow E, R(-1) \rightarrow Q$ (Pattern is $+1$ for first letter, then adjustments).
For TIGER: $T(+1)=U, I(-1)=H, G(+1)=H, E(-1)=D, R(+1)=S$ .

Part 3: Current Affairs (Feb 2026 Updates)

Question 5: (Environment)

Which Indian city hosted the "International Green Hydrogen Summit" in the first week of February 2026?
