The correct answer is C
? ÷ [35% of 379 - 34(4/5)] = 0.4
(? × 3)2 - 85 = 115 × 5 + 69
40 of 30% of 220 = ? + 790
32 × 3 (54 – 15) + 186 ÷ 3 ÷ 2 – (21)² =?
√(?) ² = √7396 - √6889
(75 + 0.25 × 10) × 4 = ?2 - 14
If x - 1/x = 9, then the value of x² + 1/ x² is:
√144 × √121 + 25% of 600 = ? + 256
[123 ÷ 8 ÷ 9] × 144 = ? + 12 × 5
132 × 3 ÷ 11 + 67 − ? = 64 ÷ 8 × 2
