If '+' stands for division, 'x' stands for subtraction ÷  stands for multiplication '-' stands for addition, then which value of a correct following equation?

20 ÷ 5 - 16 + 8 x 4 = 2a

  1. AOption (a)

    38

  2. BOption (b)

    49

  3. COption (c)

    39

  4. DOption (d)

    47

View answer & explanation

Correct answer

Answer: (b)B.

49

Why this answer is correct

BODMAS Table: 

Given equation: 20 ÷ 5 - 16 + 8 x 4 = 2a

SymbolMeaning
+÷
x-
÷×
-+

Now, replacing the symbols:

⇒ 20 × 5 + 16 ÷ 8 - 4 = 2a

⇒ 20 × 5 + 16 ÷ 8 - 4 = 2a

⇒ 100 + 16 ÷ 8 - 4 = 2a

⇒ 100 + 2 - 4 = 2a

⇒ 100 + 2 - 4 = 2a

⇒ 102 - 4 = 2a

⇒ 98 = 2a

⇒ a = 49

Hence, the correct answer is "Option 2".

Why this answer is correct

The logic followed here is the chronological sequence of steps involved in withdrawing money from an ATM machine.

Logical Sequence:

  1. Insert card (3): This is the initial step to start any transaction at an ATM.
  2. Enter pin (1): After the card is read, the system asks for the Personal Identification Number (PIN) for authentication.
  3. Enter amount (2): Once the PIN is verified, the user inputs the amount of money they wish to withdraw.
  4. Receive cash (4): The machine processes the request and dispenses the money, which is the final step.

 

The correct order is 3 → 1 → 2 → 4.

Hence, the correct answer is “Option 3”.

Question 573

Find out total number of triangles in the given diagram?

  1. AOption (a)

    60

  2. BOption (b)

    360

  3. COption (c)

    240

  4. DOption (d)

    220

View answer & explanation

Correct answer

Answer: (c)C.

240

Why this answer is correct

Triangles in the given figure,

In one part of this figure:

Number of triangles in one part = 15 + 15 + 15 + 15 = 60

Now,

Given figure having 4 symmetrical parts.

Total triangles = 4 × 60 = 240

Hence, the correct answer is “Option 3”.

Question 574

Delhi Police Head Constable 2025• General Intelligence

A pair of numbers or symbols is given that follows a particular logic or pattern. Examine the relationship between them and select the option that reflects the same kind of relationship in its pair.

10 : 142 :: 17: 359 :: 21 : ?

  1. AOption (a)

    525

  2. BOption (b)

    576

  3. COption (c)

    529

  4. DOption (d)

    527

View answer & explanation

Correct answer

Answer: (d)D.

527

Why this answer is correct

The pattern observed is: (First Number + 2)2 − 2.

For 10 : 142 →

(10 + 2)2 − 2 = 144 − 2 = 142

For 17 : 359 →

(17 + 2)2 − 2 = 361 − 2 = 359

Similarly,

let's find the missing number for 21 : ? →

(21 + 2)2 − 2 = 529 − 2 = 527

Hence, the correct answer is “Option 4”.

Question 575

Delhi Police Head Constable 2025• General Intelligence

In the following question, a pair of figures on the left is related to each other in a particular way. Find the figure from the options that completes the second pair so that the same relationship holds between the second pair as in the first. Choose the correct option.

RAMP : IZNK : CEILING : ?

  1. AOption (a)

    XVRORMT

  2. BOption (b)

    XVTRPNL

  3. COption (c)

    WUQNQLS

  4. DOption (d)

    YWSPSNU

View answer & explanation

Correct answer

Answer: (a)A.

XVRORMT

Why this answer is correct

The logic followed here is based on opposite letter pairs, where the sum of the positional values of two letters is 27.

For RAMP to IZNK

R(18)A(1)M(13)P(16)
↓ Opp.↓ Opp.↓ Opp.↓ Opp.
I(9)Z(26)N(14)K(11)

In this pattern, 18 + 9 = 27, 1 + 26 = 27, 13 + 14 = 27, and 16 + 11 = 27.

For CEILING to ?

Applying the same Opposite Pair logic (Sum = 27) to CEILING:

C(3)E(5)I(9)L(12)I(9)N(14)G(7)
↓↓↓↓↓↓↓
X(24)V(22)R(18)O(15)R(18)M(13)T(20)

The letters obtained are XVRORMT.

Hence, the correct answer is 'Option 1'.

Question 576

Delhi Police Head Constable 2025• General Intelligence

In the following question, four words are given, out of which three are similar in meaning or belong to the same category or group. Identify the word that does not belong to the group. Choose the option that is different from the others based on semantic classification.

  1. AOption (a)

    Hydrogen

  2. BOption (b)

    Oxygen

  3. COption (c)

    Carbondioxide

  4. DOption (d)

    Nitrogen

View answer & explanation

Correct answer

Answer: (c)C.

Carbondioxide

Why this answer is correct

Here,

Hydrogen, Oxygen, and Nitrogen are all fundamental chemical elements found on the periodic table. They are substances that consist of only one type of atom.

While,

Carbondioxide is a chemical compound. A compound is a substance formed when two or more different elements (in this case, Carbon and Oxygen) are chemically bonded together.

Therefore, Carbondioxide is the odd word that does not belong to the group.

Hence, the correct answer is “Option 3”.

  4. DOption (d)
    • , x, +, ÷, =
View answer & explanation

Correct answer

Answer: (a)A.

÷, -, +, x, =

Why this answer is correct

Given equation: 100 * 10 * 5 * 2 * 3 * 11

We need to find the correct mathematical signs to insert respectively to get a correct equation, following BODMAS.

Let's check each option one by one:

Option 1) ÷, −, +, ×, =

Equation: 100 ÷ 10 − 5 + 2 × 3 = 11

⇒ 100 ÷ 10 − 5 + 2 × 3 = 11

⇒ 10 − 5 + 6 = 11

⇒ 10 − 5 + 6 = 11

⇒ 11 = 11

Since 11 = 11, this option is correct.

Option 2) +, ÷, −, ×, =

Equation: 100 + 10 ÷ 5 − 2 × 3 = 11

⇒ 100 + 10 ÷ 5 − 2 × 3 = 11

⇒ 100 + 2 − 6 = 11

⇒ 96 ≠ 11

Since 96 ≠ 11, this option is incorrect.

Option 3) ×, −, ÷, +, =

Equation: 100 × 10 − 5 ÷ 2 + 3 = 11

⇒ 100 × 10 − 5 ÷ 2 + 3 = 11

⇒ 1000 − 2.5 + 3 = 11

⇒ 1000.5 ≠ 11

Since 1000.5 ≠ 11, this option is incorrect.

Option 4) −, ×, +, ÷, =

Equation: 100 − 10 × 5 + 2 ÷ 3 = 11

⇒ 100 − 10 × 5 + 2 ÷ 3 = 11

⇒ 100 − 50 + 0.67 = 11

⇒ 50.67 ≠ 11

Since 50.67 ≠ 11, this option is incorrect.

Hence, the correct answer is "Option 1".

Question 579

Delhi Police Head Constable 2025• General Intelligence

If + = , - = /, * = +, / = - ; then, what is [{10+(42)}] - 6*3/2 ?

  1. AOption (a)

    11

  2. BOption (b)

    13

  3. COption (c)

    9

  4. DOption (d)

    12

View answer & explanation

Correct answer

Answer: (a)A.

11

Why this answer is correct

BODMAS Table: 

Given expression: [{10 + (4 * 2)}] - 6 * 3 / 2

Given SymbolActual Operation
+×
-÷
*+
/-

Now, replacing the symbols:

⇒ [{10 × (4 + 2)}] ÷ 6 + 3 - 2

⇒ [{10 × (4 + 2)}] ÷ 6 + 3 - 2

⇒ [{10 × 6}] ÷ 6 + 3 - 2

⇒ 60 ÷ 6 + 3 - 2

⇒ 10 + 3 - 2

⇒ 10 + 3 - 2

⇒ 13 - 2

⇒ 13 - 2

⇒ 11

Hence, the correct answer is "Option 1".
