Question
The ozone layer thickness is measured
in:Solution
The thickness of the ozone layer is measured in Dobson Units (DU). A Dobson Unit is a measure of the total amount of ozone in a column of air stretching from the Earth's surface to the top of the atmosphere. One Dobson Unit represents a layer of ozone that would be 0.01 millimeters thick under standard temperature and pressure conditions.
(22 + √3364)/(? + 4) = 10
28(4/5) + 52(1/2) × 8(2/7) - 11(1/5) = ? + 6(1/5)
(8.6 × 8.6 + 4.8 × 4.8 + 17.2 × 4.8) ÷ (8.62 – 4.82 ) = ? ÷ 19
The value of 42 ÷ 9 of 6 - [64 ÷  48 x 3 – 15 ÷ 8 x (11 – 17) ÷ 9] ÷ 14 is:
(21 × 51 + 81)/(9 × 14 - 30) = ?
 {(481 + 426) 2 - 4 × 481 × 426} = ?
- Find the simplified form of the following expression:
128 - 85 of 2 + 26 X 4 ?% of (168 ÷ 8 × 20) = 126
What will come in the place of question mark (?) in the given expression?
? = (27 × 13) – 26% of (412 – 92 )
82% of 400 + √(?) = 130% of 600 - 85% of 400
