A paper is folded and cut as shown in the following

(7 ÷ 0.125) x (10 ÷ 10/3 ) = ?  

120 × 195 ÷ 13 - ? = 16²

52% of 36% of 810 = 72% of 18% of ? 

If √3ⁿ 729, then the value of n is equal to:

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

(28/14) of 56 + ? = 920 ÷ 5

(3500 ÷ √1225) × √(20.25) = ? ÷ 4

7/3 of 4/5 of 15/56 of ? = 83

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

? = 70% of 36% of (25 × 320) + 150

654.056 + 28.9015 × 44.851 – 43.129 = ?
