Directions (11-15): What will come in place of question mark (?) in the following simplification problems?
Q11. 8899 – 6644 – 3322 = ? – 1122
= 10021 – 9966
Q12. (46)² – (?)² = 4398 – 3066
?² = 784
? = ±28
Q13. (800 ÷ 64) × (1296 ÷ 36) = ?
Q14. (24 + 25 + 26)² – (10 + 20 + 25)² = ?
= 20 × 130
Q15. 397 × 397 + 104 × 104 + 2 × 397 × 104 = ?
As we know,
(a + b) ² = a² + b² + 2ab
∴ ? = (397 + 104) ²
= (501) ²
