Simplify the given expression.

If 1560 ÷ 30 + 2025 ÷ 45 - z + 33 × 7 = 1848 ÷ 24 × 234 ÷ 39, then the value of z is:

2350 – 4830 + 9570 + 3350 – 1720 = ?

What should come in place of (?) question mark in the given expression.

[60% of 350 + (2/7 of 210)] ÷ 5 = ?

15% of 1800 + 2² = ? 

(7/5) × (3/4) × (5/9) × (6/7) × 3112 = ?

Determine the value of 'p' in following expression:

720 ÷ 9 + 640 ÷ 16 - p = √121 X 5 + 6²- 7
