ISO 22000 describes which management

Simplify:

(5/6 + 3/4) ÷ (7/8 − 1/3)

81% of 2300 – 34% of 550 = ?

40 of 30% of 220 = ? + 790

What will come in place of the question mark (?) in the following expression?

40% of 150 – ?% of 80 = 25% of 400

6 × 1.8 × 0.25 × 70 = ? + 9.5

500% of (121.8 + 16.4 – 28.2) = ? × 2

(500 × 6 ÷ 10) - (√256 + 8) = ?

Evaluate: 360 ÷ [ {18 − (6×2)} × 5 ] + 7² − 3³

What will come in place of the question mark (?) in the following expression?

25% of 2000 – 50% of 500 = 100% of ?
