1. It is the process of separation of components of a mixture.
2. It is used to separate colours in a dye.
3. It is used to separate a mixture of oil and water.
Select the correct answer using the codes given below.
The correct answer is C
(?)2 + 4.113 = 23.92 – 28.03
(124.99)² = ?
³√? `xx` 32.87 + 59.83 `xx` 28.7665 – 48.8745 `xx` 21.642 = 1085.344
2720.03 ÷ 79.98 x 39.9 = ? + 40.32
? + 144.99 – 120.01 = 25.01 × 6.98
(108.999)² - (102.001)²=?
6940 ÷ 28 ÷ 7 = ?
`[(sqrt(750) xx15.981) -: 54.003]` `xx` ? = 6997.81001
(88.931% of 435) + (61.521% of 516) = ?
`5(17/23)` + `1(15/46)` - `5(17/25)` = ? - `6(13/23)`
