413.	Salaries of Ravi and Ankit are in the ratio 5 : 7. If the salary of each is increased by Rs. 6,000. The new ratio becomes 11 : 15, what is the sum of salary of Ravi and Ankit?1. Rs. 1,10,0002. Rs. 1,50,0003. Rs. 1,44,0004. Rs. 1,76,8005. Rs. 1,40,000
Answer» Correct Answer - Option 3 : Rs. 1,44,000 Given: Salaries of Ravi and Ankit are in the ratio 5 : 7 The salary of each is increased by Rs. 6000 Calculation: Let the original salaries of Ravi and Ankit be Rs. 5x and 7x respectively. Then, ⇒ (5x + 6000)/(7x + 6000) = 11/15 ⇒ 15(5x + 6000) = 11(7x + 6000) ⇒ 75x + 90000 = 77x + 66000 ⇒ 2x = 24000 ⇒ x = 12000 Total salary of Ravi and Ankit = 5x + 7x ⇒ 5 × 12000 + 7 × 12000 ⇒ Rs. 1,44,000 ∴ The sum of salary of Ravi and Ankit is Rs. 1,44,000.

Salaries of Ravi and Ankit are in the ratio 5 : 7. If the salary of each is increased by Rs. 6,000. The new ratio becomes 11 : 15, what is the sum of salary of Ravi and Ankit?1. Rs. 1,10,0002. Rs. 1,50,0003. Rs. 1,44,0004. Rs. 1,76,8005. Rs. 1,40,000

Answer» Correct Answer - Option 3 : Rs. 1,44,000

Given:

Salaries of Ravi and Ankit are in the ratio 5 : 7

The salary of each is increased by Rs. 6000

Calculation:

Let the original salaries of Ravi and Ankit be Rs. 5x and 7x respectively.

Then,

⇒ (5x + 6000)/(7x + 6000) = 11/15

⇒ 15(5x + 6000) = 11(7x + 6000)

⇒ 75x + 90000 = 77x + 66000

⇒ 2x = 24000

⇒ x = 12000

Total salary of Ravi and Ankit = 5x + 7x

⇒ 5 × 12000 + 7 × 12000

⇒ Rs. 1,44,000

∴ The sum of salary of Ravi and Ankit is Rs. 1,44,000.

416.	The purest form of iron is prepared by oxidising impurities from cast iron in a reverberatory furnace. Which iron ore is used to line the furnace? Explain by giving reaction.
Answer» Haematite ore `(Fe_(2)O_(3))` is used to line blast furnace. It oxidises carbon present in cast iron upon heating to form carbon monoxide (CO). By doing so, the carbon contents decrease from (2.5 to 4.5%) in cast iron to about 0.2 to 0.5 %. This variety of iron is known as wrought iron. It is the purest form of iron. `Fe_(2)O_(3)(s) +3C(s) overset("heat") to 2Fe(s) +3CO(g)`

Answer» (a) Activated carbon or activated charcoal is an extremely porous carbon that has a very large surface area available for adsorption or chemical reactions. It is the most widely used adsorbent for preparing gas masks to selectively adsorb toxic gases. (b) The coagulation will take place when FeCl₃ is added to NaOH solution. The Fe(OH)₃ gets coagulated by the oppositely charged particle Cl⁻ . (c) Adsorption is always accompanied by evolution of heat, so according to Le Chatelier’s principle, the magnitude of adsorption should increase with a decrease in temperature. In chemisorption since it requires some activation energy, the magnitude of adsorption increases initially and then decreases with an increase in temperature
