Evaluate: (768÷16)×(125÷25)−(81÷9)×12
Determine the simplified value of the given mathematical expression.
If a nine-digit number 389x6378y is divisible by 72, then the value of √(6x + 7y) will be∶
(47.5 ÷ 9.5) × (78.5 ÷ 15.7) + 475 = ? + 15% of 150
If 840 ÷ 12 + 1025 ÷ 25 - n + 45 × 4 = 960 ÷ 16 × 132 ÷ 44, then the value of n is:
3/7 of 504 ÷ 12 + 17 = √?
 √256 * 4 – 30% of 190 + ? = 110% of 220
(70% of 480) ÷ 6 + ? = 45% of 3500 + 802 + 272
32 X 25 ÷ 4 + 12 of 30 = ? X 5 - 30Â
