Consider the following statements for fluidized bed boilers: 1. Fluidized bed boilers produce steam from fossil and waste fuels by using a technique called fluidized bed combustion. 2. Cyclone separators are gas cleaning devices that utilize the centrifugal force created by a spinning gas stream to separate particles from a gas. 3. In a pressurized fluidized bed boiler, the combustion process takes place in a pressurized environment resulting in a compact furnace and improved combustion efficiency. Which of the above statements are correct?

A

1 and 2 only

B

2 and 3 only

C

1 and 3 only

D

1, 2 and 3

Bottled water is drinking water (e.g., well water, distilled water, mineral water, or spring water) packaged in PET Bottle or Glass Water Bottles. Bottled water is comprehensively regulated by the U.S. Food and Drug Administration (FDA) as a packaged food product. By law, the FDA regulations for bottled water must be at least as stringent as the Environmental Protection Agency standards for tap water. What inference can be drawn from the above passage?

A

Bottled water is more expensive than tap water.

B

Bottled water is more nutritious than tap water.

C

Tap water is monitored by the FDA.

D

Bottled water can pose an environmental risk.

A three-star medicine is prepared by mixing two type of fluids (A & B) in ratio of 1 : 4. Fluid A is prepared by mixing two type of water, water M and water N in ratio of 4 : 5. Fluid B is prepared by mixing two type of water, water X and water N in ratio of 3 : 7. The final mixture is prepared by 675 units of three-star medicine with water Y. If the concentration of the water N in the final mixture is 60%, then how much water Y had been added to three-star medicine?

A

305

B

355

C

302
