30 of 20 - 40 + 182 - 23 × ? = 8³ 

The sum of two numbers is 16 and their product is 63. The sum of their reciprocal is equal to:

What value should come in the place of (?) in the following questions?

16² – 12 * 20 = 6 * ? - ³√8000

Find the simplified value of the given expression:

(744 ÷ 6) - (120/5) + 5.5% of 800 = ?²

25% of 12% of 1600 + 112 = ? × 4 

15% of 1800 + 2² = ? 

40 of 30% of 220 = ? + 790

2/5 of 3/4 of 7/9 of 7200 = ?
