Answer 1. (C) 203

Explanation:

24 × 0.5 ÷ .06 − 6 = ? − 9

12 ÷ .06 − 6 = ? − 9

200 − 6 + 9 = ?

? = 203

 

Answer 2. (A) 70

Explanation:

35 − 2 × 17 + 54 ÷ 6 = ? ÷ 7

35 − 34 + 9 = ? ÷ 7

1 + 9 = ? ÷ 7

10 = ? ÷ 7

? = 10 × 7 = 70

 

Answer 3. (E) 4.2 

Explanation:

80% of 56 − 27 ÷ 2 × 3 + ? = 17 ÷ 2

44.80 − 40.5 + ? = 8.5

4.3 + ? = 8.5

? = 8.5 − 4.3

? = 4.2

 

Answer 4. (B) 6

Explanation:

(0.3)4 ÷ (90)2 × (30)4 ÷ (.9)2 = 3?−6

(3)4 ÷ (10)4 ÷ (9)2 ÷ (10)2 × (3)4 × (10)4 ÷ (9)2 ÷ (10)2 = 3?−6

(3)4 ÷ (32)2 × (3)4 ÷ (32)2 = 3?−6

1 = 3?−6

30 = 3?−6

0 = ? − 6

? = 6

 

Answer 5. (D) 80

Explanation:

2349 + 1619 − 768 = ? × 40

3968 − 768 = ? × 40

3200 = ? × 40

? = 80
