Determine the simplified value of the given mathematical expression.
721 +21 x 9 - 118 = ? + 82
Solve: 3/4÷2/3 ​
? = (22% of 25% of 60% of 3000) + 21
22% of 280 + 34% of 1080 × 5/12 =? + 16% of 460
Simplify the following expression:

What will come in the place of question mark (?) in the given expression?
? = 60% of 48% of (20 × 350) + 180
654.056 + 28.9015 × 44.851 – 43.129 =?
What will come in place of the question mark (?) in the following expression?
25% of 2000 – 50% of 500 = 100% of ?
Find the simplified value of the following expression:
[{12 + (13 × 4 ÷ 2 ÷ 2) × 5 – 8} + 13 of 8]
