Question
If 84 × 13 = 8, 37 × 13 = 6, 26 × 11 = 6, then 56 ×
22 = ?Solution
The logic is:
84 x 13 = 8             (8 +4) – (1+3) = 12-4 =8
37 x 13 =6         (3+ 7) – (1+3) = 10-4 =6
26 x 11 =6              (2+ 6) – (1+1) = 8 -2 = 6 Similarly,
56 x 22 = ?             (5 + 6) – (2+2) = 11-4 =7 Hence ‘7’ is the correct answer

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
