Potassium bromide is a salt used to make photographic papers and plates and for process engraving. Gunpowder, also known since the late 19th century as black powder, is a mixture of sulphur, charcoal, and potassium nitrate (saltpeter)—with the sulphur and charcoal acting as fuels, while the saltpeter works as an oxidizer. The principal use of potassium sulphate is as a fertilizer. K₂SO₄ does not contain chloride, which can be harmful to some crops. Potassium sulphate is preferred for these crops, which include tobacco and some fruits and vegetables. A white, acid, crystalline solid or powder, KHC₄H₄O₆, used in baking powder, in the tinning of metals, and as a component of laxatives. Also called cream of tartar.

The correct answer is D as
 R = ((1, 1), (3, 1), (2, 3), (4, 2))
RoR=R²=((1, 1), (3, 1), (2, 3), (4, 2))((1, 1), (3, 1), (2, 3), (4, 2))
     =((1, 1), (3, 1), (2, 1), (4, 3))
take the first set (1,1) then take the second element of this subset check in the other set R is there any starting with 1 if yes then take its second element and make a subset in R² similarly check for all.
like (4,2) (2,3)=(4,3)in R²

According to the question, 

Given information is, Twenty-five boxes of sweets are delivered to Mr Roy's home. Mr Roy had ordered three different types of sweets. What is the minimum number of boxes of sweets that are having sweets of same type?

Since Mr Roy has ordered for 25 boxes and there different types of sweets, minimum 9 boxes of sweets will have the same type of sweets.

Hence, the answer is 9.

Three resistors of 2Ω is required to get 6Ω because resultant is more than individual so they all must be connected in parallel.

Total number of balls = 3 + 5 + 4 = 12

Let S be the sample space.
n(S) = Total number of ways of drawing 3 balls out of 12 = ¹²C₃

Let E = Event of drawing 3 different coloured balls

To get 3 different coloured balls,we need to select one black ball from 3 black balls,
one red ball from 5 red balls, one blue ball from 4 blue balls

Number of ways in which this can be done = ³C₁ × ⁵C₁ × ⁴C₁
i.e., n(E) = ³C₁ × ⁵C₁ × ⁴C₁

• April 13 saw celebrations for the Sikh festival of Baisakhi, which marks the onset of Spring and the harvest of winter crops. Simultaneously, the movement for independence from British rule had been steadily gaining ground.

Option A: In the sprinkler system the perpendicular pipes, having rotating nozzles on top, are joined to the main pipeline at regular intervals. When water is allowed to flow through the main pipe under pressure with the help of a pump, it escapes from the rotating nozzles. It gets sprinkled on the crop as if it is raining.
Option B: Pulley system is traditional irrigation methods where water is lifted from wells or other water sources and crops are watered. This is done by using the pulley chain and human labour or animals.
Option C: Lever system is traditional irrigation methods where humans or animals are used to lift the water from its source. This is a less efficient method for irrigation.
Option D: Drip irrigation is a much more controlled irrigation method. It works by exposing the roots to a direct supply of water. This method is facilitated by the use of drip emitters, which release water in a slow and steady fashion.

Thus, option D is correct.

• A solar eclipse occurs when the Moon is positioned in between the Sun and the Earth for a few minutes. Under certain-alignment, the Moon partially or fully blocks the Sun’s light and instead casts its shadow on Earth. That is why, there can be a partial or a total solar eclipse, depending on how much portion of the Sun’s disc gets hidden by the Moon.
• Use of certified solar filters or eclipse goggles are recommended while viewing the Sun during the eclipse.
• Experts warn against looking at the Sun with naked eyes, or through binoculars or telescopes without filters, as this can prove harmful to one’s vision. The safest way to view the eclipse is by indirect projection method, which can be easily done by projecting the Sun’s disc onto a white paper, either using a telescope or a pin-hole camera.

• Three dimensional (3D) bioprinting is the utilization of 3D printing–like techniques to combine cells, growth factors, and/or biomaterials to fabricate biomedical parts, often with the aim of imitating natural tissue characteristics. Generally, 3D bioprinting can utilize a layer-by-layer method to deposit materials known as bio-inks to create tissue-like structures that are later used in various medical and tissue engineering fields.
• There are many applications for 3D bioprinting in the medical field. An infant patient with a rare respiratory disease known as tracheobronchomalacia (TBM) was given a tracheal splint that was created with 3D printing. 3D bioprinting can be used to reconstruct tissue from various regions of the body. 

Let the cost price of a ball be Rs. x.

So, the CP of 17 balls is Rs. 17x.

The CP of 5 balls is Rs. 5x.

Since Loss = CP - SP

So, 5x = 17x - 720

On solving, we get

12 x = 720

that is, x = 60

So, the cost price of a ball is Rs. 60.
