68Â Â Â 69Â Â Â Â 65Â Â Â 74Â Â Â
 ?      83    47Solution
The series is: 68 + 12 = 69 69 – 22 = 65 65 + 32 = 74 74 – 42 = 58 58 + 52 = 83 83 – 62 = 47
41.66% of 888 + 66.66% of 1176 = ?2 - 4√ 16 Â
Evaluate: 320 − {18 + 4 × (21 − 9)}
Simplify: 72 ÷ 6 × 3 − 8 + 4
118 × 6 + 13 + 83 = ?
Simplify the following expression:
  (400 +175) ² - (400 – 175) ² / (400 × 175)
150% of 850 ÷ 25 – 25 = ?% of (39312 ÷ 1512)
(75 + 0.25 × 10) × 4 = ?2 - 14
26% of 650 + 15% of 660 – 26% of 450 = ?
115% of 40 + 3 × 4 = ? × 11 – 8
