300 ÷ 12 of 5 + 250 ÷ 10 × 5 = ?
125
150
130
200
135
Correct answer
130
Why this answer is correct
Concept used:
Calculation:
300 ÷ 12 of 5 + 250 ÷ 10 × 5 = ?
300 ÷ (12 × 5) + 250 ÷ 10 × 5 = ?
300/60 + 250/10 × 5 = ?
5 + 125 = 130 = ?
∴ The value of '?' is 130.
What will come in the place of ‘?’ in the following question?
157 – 700 × 3% of 2 – 13 × 5 = ?
65

50
45
Correct answer
50
Why this answer is correct
Concept used:
Calculation:
157 – 700 × 3% of 2 – 13 × 5 = ?
157 – 700 × (3/100 × 2) – 13 × 5 = ?
157 – 700 × 6/100 – 13 × 5 = ?
157 – 42 – 65 = ?
? = 50
∴ The value of '?' is 50.
What will come in the place of the question mark '?' in the following question?
0.360 ÷ 1.8 ÷ 0.25 × 100 – 42 = ?2
4
6
8
10
2
Correct answer
8
Why this answer is correct
Concept used:
Follow BODMAS rule to solve this question, as per the order given below,
Calculation:
0.360 ÷ 1.8 ÷ 0.25 × 100 —42 = ?2
0.36/(1.8 × 0.25) × 100 —16 = ?2
0.36/0.45 × 100 — 16 = ?2
0.8 × 100 — 16 = ?2
80 —16 = ?2
64 = 82 = ?2
? = 8
∴ The value of '?' is 8.
What will come in the place of the question mark '?' in the following question?
(100 + 400 ÷ 2 of 0.25 – 250) ÷ ? = 50
11
12
13
14
15
Correct answer
13
Why this answer is correct
Concept used:
Follow BODMAS rule to solve this question, as per the order given below,
Calculation:
(100 + 400 ÷ 2 of 0.25 – 250) ÷ ? = 50
[100 + 400 ÷ (2 × 0.25) – 250] ÷ ? = 50
[100 + (400/0.5) – 250]/? = 50
(100 + 800 – 250)/? = 50
650/? = 50
? = 650/50 = 13
∴ The value of '?' is 13.
What will come in the place of the question mark '?' in the following question?
[(272 – 32) × (124 + 176)]/(17 × 15 – 15) = ?
240
320
400
380
300
Correct answer
300
Why this answer is correct
Concept used:
Follow BODMAS rule to solve this question, as per the order given below,
Calculation:
[(272 – 32) × (124 + 176)]/(17 × 15 – 15) = ?
⇒ (240 × 300)/(255 – 15) = ?
⇒ (240 × 300)/240 = ?
⇒ 300 = ?
∴ The value of ? is 300
What will come in the place of the question mark ‘?’ in the following question?
873.53 + 532.32 – ? = 535.1 + 232.95
627.8
627.5
637.5
637.8
636.5
Correct answer
637.8
Why this answer is correct
Concept used:
Follow BODMAS rule to solve this question, as per the order given below,

45
50
55
25
60
Correct answer
55
Why this answer is correct
Given
30% of 450 – 33.33% of 270 + x = 100
Concept used
Bodmas concept is used
Calculation
30% of 450 - 33.33% of 270 + ? = 100
⇒ (30/100) × 450 - (1/3) × 270 + ? = 100
⇒ 135 - 90 + ? = 100
⇒ 45 + ? = 100

[(4/5 of 360 + 2/7 of 126) – (45 × 4 + 32 × 3/8)]
Concept used:
Follow the BODMAS rule according to the table given below:
Calculation:
Using the BODMAS rule
⇒ [(4/5 of 360 + 2/7 of 126) – (45 × 4 + 32 × 3/8)] = ?
⇒ [(4/5 × 360 + 2/7 × 126) – (45 × 4 + 32 × 3/8)] = ?
⇒ [(288 + 36) – (45 × 4 + 32 × 3/8)] = ?
⇒ [324 – (45 × 4 + 32 × 3/8)] = ?
⇒ [324 – (180 + 32 × 3/8)] = ?
⇒ [324 – (180 + 12)] = ?
⇒ [324 – (192)] = ?
⇒ ? = 132
∴ 132 will come in place of ‘?’
What will come in the place of the question mark ‘?’ in the following question?

\({3 {47\over 84}}\)
Why this answer is correct
Given:
4/7 × 35/16 + 23/14 – 3/2 + (4/5 ÷ 24/65)
Concept used:
Follow the BODMAS rule according to the table given below:
Calculation:
Using the BODMAS rule
⇒ 4/7 × 35/16 + 23/14 – 3/2 + (4/5 ÷ 24/65) = ?
⇒ 4/7 × 35/16 + 23/14 – 3/2 + (13/6) = ?
⇒ 5/4 + 23/14 – 3/2 + (13/6) = ?
⇒ (35 + 46)/28 – 3/2 + (13/6) = ?
⇒ 81/28 – 3/2 + (13/6) = ?
⇒ 81/28 + (13/6) – 3/2 = ?
⇒ (243 + 182)/84 – 3/2 = ?
⇒ (425 – 126)/84 = ?
⇒ (299)/84 = ?
⇒ ? = \({3 {47\over 84}}\)
∴ \({3 {47\over 84}}\) will come in place of ‘?’
