• Calculate the number of roses: 5% of 5000 plants = 0.05 * 5000 = 250 roses


• Calculate the number of marigold: 1% of 5000 plants = 0.01 * 5000 = 50 marigold

• Dissolution of Oxygen in water: This is a physical change as it involves the formation of a homogeneous mixture of oxygen gas and water molecules without any chemical reaction taking place. The properties of both oxygen and water remain the same.


• Dissolution of Carbon dioxide in water: This is also a physical change as it involves the formation of a homogeneous mixture of carbon dioxide gas and water molecules without any chemical reaction occurring. The properties of both carbon dioxide and water remain unchanged.


• Dissolution of salt in water: This is a chemical change as it involves the breaking of ionic bonds in the salt crystals and the formation of new bonds between the salt ions and water molecules. The properties of the salt and water change in this process.


• None of the above: This option is not correct as the dissolution of salt in water is a chemical change, unlike the dissolution of oxygen and carbon dioxide which are physical changes.

Calculation:

Given:
- 15 boys earn Rs. 900 in 5 days
- We need to find out how much 20 boys will earn in 7 days

Calculation:

- Let's first calculate the daily earning of 1 boy:
- Daily earning of 1 boy = Rs. 900 / 15 boys / 5 days
- Daily earning of 1 boy = Rs. 900 / 75
- Daily earning of 1 boy = Rs. 12

- Now, let's calculate the total earning of 20 boys in 7 days:
- Total earning of 20 boys in 1 day = 20 boys * Rs. 12
- Total earning of 20 boys in 1 day = Rs. 240
- Total earning of 20 boys in 7 days = Rs. 240 * 7
- Total earning of 20 boys in 7 days = Rs. 1680

Therefore, 20 boys will earn Rs. 1680 in 7 days. So, the answer is option D: Rs. 1680.

• Heat sensitivity: Vitamin C is very sensitive to heat and can be easily destroyed when exposed to high temperatures.


• Water solubility: Being water-soluble, Vitamin C can leach out into cooking water if fruits or vegetables are boiled, leading to loss of the vitamin.


• Oxidation: Vitamin C is also sensitive to oxidation, which can occur during cooking processes like frying or baking.


• Length of cooking time: Prolonged cooking can further degrade Vitamin C content in foods.


• Food processing: Processing methods like canning or freezing can also lead to loss of Vitamin C in foods.

Upstream Speed = 2/(20/60) = 6 kmph

Downstream Speed = 2/(15/60) = 8 kmph

Speed of boat = (Downstream Speed + Upstream Speed)/2 = 14/2 = 7 kmph

Speed of current = (Downstream Speed - Upstream Speed)/2 = 2/2= 1 kmph
