Minimum Possible diagram is-

Conclusions:

I. Some wires are equipment. (It follows because All equipment are wires.)

II. No speakers is wire. (It does not follow as All speakers are equipment and All equipment are wires.)

III. Some speakers are not wires. (It also does not follow as All speakers are equipment and All equipment are wires.)

So, Only conclusion I follows.

Hence, option B is the correct answer.

In a plane mirror, a mirror image is a reflected duplication of an object that appears almost identical, but it is reversed in the direction perpendicular to the mirror surface. As an optical effect it results from reflection of substances such as a mirror or water.

Hence, option D is the correct answer.

Similarly,

Hence, option D is the correct answer.

Here the smallest number which is divisible by 6, 9, 15, 18 is LCM of these numbers

LCM of 6, 9, 15, 18 is 90.

So, the number smallest number which when divided by 6, 9, 15, 18 leaving remainder 4 is:

LCM + 4

= 90 + 4 = 94

Now this number should be divisible by 7.

So general number (90 k + 4) must be divisible by 7.

 for k = 4, 6k + 4 is divisible by 7 and hence 90k + 4 is

divisible by 7.

Required number is 364.

Mirza Gulam Ahmad established the Ahamdiyya Movement around 1889.

• It was based on liberal principles and played the similar role as played by Brahmo samaj in Hindu Society.

• They believed in separating Religion from State for development of society.

• The Islets of Langerhans are part of Pancreas. They make 1 to 2% of the pancreas volume.

• These are discovered by Paul Langerhans in 1869.

• These cells are responsible for the production and release of hormones that regulate glucose level.

• Deacon Process is a process to produce Chlorine gas. It was discovered by Henry Deacon.

• In this Hydrogen Chloride is converted to Chlorine gas.

CHLORINE:

• It is second lightest Halogen and is a strong oxidising agent.

• It is used in water purification, cleaning swimming pools & as a disinfector.

• High concentrated Chlorine is a poisonous gas and was used in World War I.
