Answer 1

Answer:

pls mark me as Braniliest

Step-by-step explanation:

Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. ... Heat from the sun, or solar energy, powers the evaporation process.

Answer 2

Answer:

Short Trick:

MP of the cooler = Rs 13200 × 100/88 × 100/75 = Rs 20000

∴ Required percentage = 2400/20000 × 100% = 12%

Detailed Solution:

Let marked price of the cooler be 100x

⇒ Vinay bought the cooler at = Rs 100x(1 – 25/100) = Rs 75x

⇒ Vinay sold the cooler at = Rs 75x(1 – 12/100) = Rs 66x

According to the question,

66x = 13200

⇒ x = 200
