Test: Mathematical Operations - Bank Exams MCQ

35 + 63 ÷ 7 - 4

⇒ 35 + 9 - 4

⇒ 40.

Hence, the option B is correct.

= 8 × 8 + 8 ÷ 8 – 8

= 8 × 8 + (8/8) – 8

= 64 +1 – 8 = 57.

17 × 11 + 12 ÷ 6

⇒ 187 + 2

⇒ 189.

Hence, the option A is correct.

a) 20 – 40 + 4 + 8 × 2000

• Transforms to: 20 + 40 × 4 × 8 > 2000

• Compute LHS: 40 × 4 = 160; 160 × 8 = 1280; 20 + 1280 = 1300

• Check: 1300 > 2000 → false

b) 9 × 10 + 4 < 8 ÷ 3 - 1

Using the rules: + → ×, < → ÷, ÷ → −, – → +, × → >
Transforms to: 9 > 10 × 4 − 8 − 3 + 1

Compute RHS:
10 × 4 = 40 → 40 − 8 = 32 → 32 − 3 = 29 → 29 + 1 = 30

Check: 9 > 30 → false

(c) 20 < 2 + 10 ÷ 4 – 6 × 100
= (20 ÷ 2 × 10 − 4 + 6) > 100
= (10 × 10 − 4 + 6) > 100
= (100 − 4 + 6) > 100
= 102 > 100 → true

(d) 18 < 5 + 12 ÷ 4 – 2 × 50
= (18 ÷ 5 × 12 − 4 + 2) > 50
= (3.6 × 12 − 4 + 2) > 50
= (43.2 − 4 + 2) > 50
= 41.2 > 50 → false

12 + 6 × 8 - 65 ÷ 5

⇒ 12 + 48 - 13

⇒ 60 - 13

⇒ 47.

Hence, the option C is correct.

45 ÷ 9 × 3 + 15 – 2.

= 5 × 3 + 15 – 2.

= 15 + 15 – 2 = 28.

19 + 3 - 7 ÷ 2 × 6

Hence, the option A is correct.

30 ÷ 6 × 5 + 4 – 2 = 27

→ 5 × 5 + 4 – 2 = 27.

→ 29 – 2 = 27.

→ 27 = 27.

Here’s the step-by-step, strictly left-to-right (no precedence):

1. 25 A 37 becomes 25 + 37 = 62

2. 62 C 2 becomes 62 × 2 = 124

3. 124 B 4 becomes 124 ÷ 4 = 31

4. 31 R 1 becomes 31 – 1 = 30

12 × 4 - 9 ÷ 3 + 3

⇒ 48 - 3 + 3
 
⇒ 48.

Hence, the option B is correct.
