Answer»

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

STEP - 1 - Parts of an equation enclosed in 'Brackets' must be solved first, and in the bracket, the BODMAS rule must be FOLLOWED,

Step - 2 - Any mathematical 'Of' or 'Exponent' must be solved next,

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.

Now, given expression:

⇒ 77.59 – 41.55 + 79.73 = ? + 62.42

⇒ ? = 77.59 - 41.55 + 79.73 - 62.42

⇒ ? = 77.59 + 79.73 - 41.55 - 62.42

⇒ ? = 53.35

√? + 36.09% of 350 - 15.998 × 22.015 = -(14)21). 9612). 10243). 9004). 841

Answer»

√? + 36.09% of 350 - 15.998 × 22.015 = -(14)2

Approximating the values to the NEAREST integer & replacing '?' by 'x'.

⇒ √x+ (36/100) × 350 - 16 × 22 = -196

⇒ √x + 126 – 352 = -196 

⇒ √x = -196 - 126 + 352 

⇒ √x = 30 

⇒ x = 302 

⇒ x = 900

Answer»

Follow BODMAS rule to solve this QUESTION, as PER the order given below,

Step-1: Parts of an EQUATION enclosed in 'Brackets' must be solved first, and in the bracket,

Step-2: Any mathematical 'Of' or 'Exponent' must be solved next,

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.

Given expression is,

9 ÷ 16 + 8.2 × 0.75 - {0.2 - (1 - ?)} = 0.0875

⇒ 9 ÷ 16 + 8.2 × 0.75 - {? - 0.8} = 0.0875

⇒ 0.5625 + 8.2 × 0.75 - {? - 0.8} = 0.0875

⇒ 0.5625 + 6.15 - {? - 0.8} = 0.0875

⇒ 6.7125 - ? + 0.8 = 0.0875

⇒ 7.5125 - ? = 0.0875

⇒ 7.5125 - 0.0875 = ?

∴ ? = 7.425

Answer»

USING the BODMAS rule,

B – Bracket in order (), {}, []

O – of

D – Division

M – Multiplication

A – Addition

S - Subtraction

(4 × 6 – 18 ÷ 3) × [192 ÷ {(5 + 3) × 4} – 2]

⇒ 18 × [192 ÷ 32 – 2]

⇒ 18 × [6 – 2]

⇒ 18 × 4

∴ (4 × 6 – 18 ÷ 3) × [192 ÷ {(5 + 3) × 4} – 2] = 72

6.

1). 202). 253). 404). 15

Answer»

Approximating the values to the NEAREST integer:

65.40 ≈ 65, 2.10 ≈ 2 and 64.33 ≈ 64

35.10 ≈ 35, 5.98 ≈ 6

⇒ (65.40 × 2.10) + 64.33% of 900 = 35.10 × ? + 5.98

⇒ (65 × 2) + 64% of 900 = 35 × ? + 6

⇒ 130 + (64/100) × 900 = 35 × ? + 6

⇒ 130 + 64 × 9 = 35 × ? + 6

⇒ 130 + 576 = 35 × ? + 6

706 = 35 × ? + 6

⇒ ? × 35 = 700

⇒ ? ≈ 20

1). \(1\frac{5}{6}\)2). \(2\frac{1}{6}\)3). \(3\frac{1}{2}\)4). \(2\frac{1}{2}\)

Answer»

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

Step - 1 - Parts of an equation ENCLOSED in the ‘BRACKETS’ MUST be solved first

Step - 2 - Any mathematical ‘OF’ or ‘EXPONEMTS’ must be solved next

Step - 3 - Next the part of the equation that contains ‘DIVISION; and ‘MULTIPLICATION’ are calculated

Step - 4 - Last but not LEAST, the parts of the equation that contains ‘ADDITION’ and ‘SUBTRACTION’ should be calculated

Now, the given expression:

⇒ $(2\frac{1}{9} \times 2\frac{2}{{19}} \DIV 6\frac{2}{3} = ? -1\frac{1}{2})$

⇒ $(\frac{{19}}{9} \times \frac{{40}}{{19}} \div \frac{{20}}{3} = ? -\frac{3}{2})$

⇒ $(\frac{{19}}{9} \times \frac{{40}}{{19}} \times \frac{3}{{20}} = ? -\frac{3}{2})$

⇒ $(\frac{2}{3} = ? - \frac{3}{2})$

⇒ $(\frac{2}{3} + \frac{3}{2} = ?)$

⇒ $(? = \frac{{13}}{6} = 2\frac{1}{6})$

Hence, the required answer is $(2\frac{1}{6})$.

Answer»

Given EXPRESSION is,

⇒ 13.50 × 1.90 + 29.98 = 114.85 - 37.80 - ?

We can write the given values as:

⇒ 1.90 ≈ 2 and 29.98 ≈ 30

⇒ 114.85 ≈ 115 and 37.80 ≈ 38

Then,

⇒ 13.5 × 2 + 30 = 115 - 38 - ?

⇒ 27 + 30 = 115 - 38 - ?

57 = 115 - 38 - ?

⇒ 57 = 77 - ?

⇒ ? = 77 - 57

∴ ? ≈ 20

Answer»

The given equation is:

6 + 36 (2.3 – 1/2) ÷ 6 - 2 + 0.5

By applying BODMAS rule,

(In BODMAS rule, B stands for BRACKETSO stands for ORDERS or powers, D stands for Division, M stands for MULTIPLICATIONA stands for Addition, S stands for Subtraction. For simplification, when we use BODMAS rule, firstly open the bracket, then resolve order, after then division, multiplication, addition and then subtraction.)

= 6 + 36 (23-5/10) ÷ 6 - 2 + 0.5

= 6 + 36 × 18/10 ÷ 6 – 2 + 0.5

= 6 + 36 × 9/5 × 1/6 – 2 + 0.5

= 6 + 54/5 – 2 + 0.5

Answer»

Given expression is,

⇒ (√1700 + 22.88) ÷ 7.89 = 8.01 × ?

We can write the given values as:

⇒ (√1700) = √(1681 + 19) = √[(41)2 + 19]

⇒ (√1700) ≈ 41

⇒ (√1700 + 22.88) ÷ 7.89 = 8.01 × ?

⇒ (41 + 23) ÷ 8 = 8 × ?

64 ÷ 8 = 8 × ?

⇒ 8 = 8 × ?

⇒ ? = 8/8 = 1

∴ ? ≈ 1

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

Step-1: PARTS of an equation enclosed in 'Brackets' must be solved first, and in the bracket,

Step-2: Any MATHEMATICAL 'Of' or 'Exponent' must be solved NEXT,

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.

Given expression is,

⇒ 192.94 + 250.01 - 81.88 = 77.44 + ?

⇒ 442.95 – 81.88 = 77.44 + ?

⇒ 361.07 = 77.44 + ?

⇒ ? = 361.07 – 77.44

∴ ? = 283.63

(43.19 × 10.19) ÷ 5.20 = 37.40 × 1.94 + ?1). 192). 123). 44). 20

Answer»

Given expression is,

(43.19 × 10.19) ÷ 5.20 = 37.40 × 1.94 + ?

We can write the given values as:

43.19 ≈ 43 and 10.19 ≈ 10

5.20 ≈ 5 and 37.40 ≈ 37 and 1.94 ≈ 2

Then,

⇒ (43 × 10) ÷ 5 = 37 × 2 + ?

430 ÷ 5 = 37 × 2 + ?

⇒ 86 = 37 × 2 + ?

⇒ 86 = 74 + ?

⇒ ? = 86 - 74

⇒ ? ≈ 12

Answer»

5/3 + 2/8 - ? × 8/2 = 4/5

⇒ ? × 8/2 = 5/3 + 2/8 - 4/5

⇒ ? × 4 = (5 × 8)/(3 × 8) + (2 × 3)/(8 × 3) - 4/5

⇒ ? × 4 = (40 + 6)/24 - 4/5

⇒ ? × 4 = (46 × 5)/(24 × 5) - (4 × 24)/(5 × 24)

⇒ ? × 4 = (230 - 96)/120

⇒ ? = 134/120 × ¼

⇒ ? = 134/480 = 67/240

331.80 ÷ 3.80 + 47.80 = 41.17% of 400 - ?1). 282). 63). 404). 15

Answer»

Given expression is,

331.80 ÷ 3.80 + 47.80 = 41.17% of 400 - ?

We can WRITE the given values as:

331.80 ≈ 332 and 3.80 ≈ 4

47.80 ≈ 48 and 41.17 ≈ 41

Then,

⇒ 332 ÷ 4 + 48 = 41% of 400 - ?

⇒ 332 ÷ 4 + 48 = (41/100) × 400 - ?

⇒ 83 + 48 = (41 × 4) - ?

⇒ 83 + 48 = 164 - ?

131 = 164 - ?

⇒ ? = 164 - 131

⇒ ? ≈ 33
