2. 968
3. 544
4. 766
5. 656

Solution:
220% of 250+150% of 144=?
550+216=?
?=766

Q6) 4 × 5² – 3² × 7 + 6² = ? + 24

1. 7²
2. 8²
3. 9²
4. 4²
5. 3²

Solution: 

4 × 5² – 3² × 7 + 6² = ? + 24
⇒ ? = 4 × 25 – 9 × 7 + 36 – 24
⇒ ? = 100 – 63 + 36 – 24
⇒ ? = 49
⇒ ? = 7²

Q7) ? = (5)³ – 3 + (4)² + (7)²

1. 185
2. 190
3. 191
4. 187
5. 201

Solution: 

? = 5³ – 3 + 4² + 7²
  = 125 – 3 + 16 + 49
  = 187

Q8) (840 ÷ 6 ÷ 4 + 79) – 1316 ÷ (19 × 5 – 48) = ?  

1. 611
2. 75
3. 86
4. -90
5. -95

Solution: 

(840 ÷ 6 ÷ 4 + 79) – 1316 ÷ (19 × 5 – 48) = ?  
⇒ (35 + 79) – 1316 ÷ (47) = ?
⇒ (35 + 79) – 28 = ?
⇒ ? = 86

Q9) 6499.91÷103.97×65.08=?

1. 4060
2. 4320
