Answer 1. (B) − 81

Explanation:

615 ÷ 15 × 41 + ? = 402

41 × 41 + ? = 1600

1681 + ? = 1600

? = 1600 − 1681

? = − 81

 

Answer 2. (E) None of these

Explanation:

520 ÷ 26 − 16 × 32 ÷ 144 × 20 = ?

20 − 9 ÷ 9 × 20 = ?

20 − 20 = ?

? = 0

 

Answer 3. (A) 189

Explanation:

621 × 15 − 30 × 27 = ? × 45

15 (621 − 2 × 27) = ? × 45

621 − 54 = ? × 3

567 = ? × 3

? = 189

 

Answer 4. (B) 12

Explanation:

(√1521 + 14 × 9 − 7 × 3) ÷ ? = 12

(39 + 126 − 21) ÷ ? = 12

144 ÷ ? = 12

? = 12
