Latest Bodmas Rule MCQ Objective Questions

Bodmas Rule Question 1:

If 395 × x = 2765, then x is -

  1. 7
  2. \(\frac{1}{7}\)
  3. 2370
  4. 3160

Answer (Detailed Solution Below)

Option 1 : 7

Bodmas Rule Question 1 Detailed Solution

- guacandrollcantina.com

Given:

395 × x = 2765

Calculation:

To isolate x, we need to divide both sides of the equation by 395:

x = 2765 / 395

x = 7

∴ The value of x is 7.

Bodmas Rule Question 2:

The value of \(2^0\times \frac{1}{2}\times 2=\)

  1. 1
  2. 0
  3. 2
  4. None of these

Answer (Detailed Solution Below)

Option 1 : 1

Bodmas Rule Question 2 Detailed Solution

Given:

20 × 1/2 × 2

Formula used:

Exponential and Multiplication rules

Calculation:

20 × 1/2 × 2

⇒ 1 × 1

⇒ 1

∴ The correct answer is option (1).

Bodmas Rule Question 3:

What value should come in the place of question mark (?) in the following question:

10620 ÷ [(3/4) (72 + 66) - 20(3/4)] = ?

  1. 110
  2. 130
  3. 120
  4. 140

Answer (Detailed Solution Below)

Option 3 : 120

Bodmas Rule Question 3 Detailed Solution

Given:

10620 ÷ [(3/4) (72 + 66) - 20(3/4)] = ?

Formula Used:

Division of fractions: a ÷ (b/c) = a × (c/b)

Order of operations (BODMAS): Brackets → Orders (powers, roots) → Division → Multiplication → Addition → Subtraction

Calculation:

10620 ÷ [(3/4) (72 + 66) - 20(3/4)] = ?

⇒ 10620 ÷ [(3/4) (138) - 60/4)] = ?

⇒ 10620 ÷ [414/4 - 60/4] = ?

⇒ 10620 ÷ 354/4 = ?

⇒ 10620 × 4/354 = ?

⇒ 120

Option 3 is the correct answer.

Bodmas Rule Question 4:

What value should come in the place of question mark (?) in the following question:

(44.7 + 347.33 + 3347.333 + 33347.333) ÷ 50 = ?

  1. 741.75
  2. 741.37
  3. 741.72
  4. 741.73

Answer (Detailed Solution Below)

Option 4 : 741.73

Bodmas Rule Question 4 Detailed Solution

Given:

Expression: (44.7 + 347.33 + 3347.333 + 33347.333) ÷ 50 = ?

Calculation:

First, sum the numbers within the parentheses:

44.700

347.330

3347.333

33347.333

Sum = 37086.696

37086.696 ÷ 50 = 741.73392 ≈ 741.73

∴ The correct answer is option 4.

Bodmas Rule Question 5:

The value of
\(\frac {3}6 + \frac {4}6 + \frac {3}{12} +\frac {2}6 - 3 =\)

  1. \(-\frac {16}{12}\)
  2. \(-\frac {22}{12}\)
  3. \(-\frac {8}{12}\)
  4. \(-\frac {15}{12}\)

Answer (Detailed Solution Below)

Option 4 : \(-\frac {15}{12}\)

Bodmas Rule Question 5 Detailed Solution

Calculation:

\(\frac {3}6 + \frac {4}6 + \frac {3}{12} +\frac {2}6 - 3 =\)

⇒ \(\frac {6}{12} + \frac {8}{12} + \frac {3}{12} +\frac {4}{12} - \frac{36}{12} =\)

⇒ \(\frac {6+8+3+4-36}{12}=\)

⇒ \(-\frac {15}{12}\)

Option 4 is the correct answer.

Solution:

We have to follow the BODMAS rule

quesImage82

Calculation:

\(? = \sqrt[5]{{{{\left( {243} \right)}^2}}}\)

 

\(⇒ ? = (243)^{\frac{2}{5}}\)

\(⇒ ? = (3 × 3 × 3 × 3 × 3)^{2⁄5}\)

\(⇒ ? = (3^5)^{2⁄5}\)

⇒ ? = 32

∴ ? = 9

Concept used:

ax × ay = ax + y

ax ÷ ay = ax - y

BODMAS

Calculation:

(4 × 4)3 ÷ (512 ÷ 8)4 × (32 × 8)4 = (2 × 2)(? + 4)

⇒ 46 ÷ (64)4 × 2564 = (4)(? + 4)

⇒ 46 ÷ (43)4 × (44)4 = (4)(? + 4)

⇒ 4(6 + 16 - 12) = (4)(? + 4)

⇒ 410 = (4)(? + 4)

So, ? + 4 = 10

⇒ ? = 10 - 4

∴ ? = 6

Bodmas Rule Question 9 Detailed Solution

Download Solution PDF

Follow BODMAS (Brackets, Of, Division, Multiplication, Addition, Subtraction) rule to solve this question, as per the order given below,

Step-1- Parts of an equation enclosed in 'Brackets' must be solved inside the bracket first,

Step-2-  Then any mathematical 'Of' or 'Exponent' must be solved,

Step-3- Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,

Step-4- Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

1251/3 × 271/3 × 1254/3 = 15 × 5?

⇒ 5 × 3 × 54 = 15× 5x

⇒ 15 × 5 4 = 15× 5x

⇒ x = 4

Hence option 4 is correct.

What should come in the place of question mark (?) in the following question?

Concept used:

Follow BODMAS rule to solve this question, as per the order given below:

image (4) (1)

\(\frac{{7.2}}{{\sqrt[3]{{0.729}}}} = \frac{{{{\left( ? \right)}^3}}}{{{{\left( 2 \right)}^3}}}\)

\(\Rightarrow \frac{{7.2}}{{\sqrt[3]{{\frac{{729}}{{1000}}}}}} = \frac{{{{\left( ? \right)}^3}}}{{{{\left( 2 \right)}^3}}}\)

\(\Rightarrow \frac{{7.2}}{{\sqrt[3]{{{{\left( {\frac{9}{{10}}} \right)}^3}}}}} = \frac{{{{\left( ? \right)}^3}}}{{{{\left( 2 \right)}^3}}}\)

\(\Rightarrow {\rm{\;}}\frac{{7.2}}{{\sqrt[3]{{{{\left( {0.9} \right)}^3}}}}} = \frac{{{{\left( ? \right)}^3}}}{{{{\left( 2 \right)}^3}}}\)

\(\Rightarrow \frac{{7.2}}{{0.9}} = \frac{{{{\left( ? \right)}^3}}}{{{{\left( 2 \right)}^3}}}\)

⇒ 8 = (?)3/(2)3

⇒ (2)3 = (?)3/(2)3

⇒ 23 × 23 = (?)3

⇒ 43 = (?)3

⇒ ? = 4

∴ The value of ? is 4.
