Question Discussion & Solution

CONCEPT:

• Supersonic speed: An object moving with a speed greater than the speed of sound is said to move with a supersonic speed.
  • Generally, a bullet fired from a gun and aircraft moves with supersonic speed. 
  • The speed of sound is about 768 miles per hour (1,236 kilometers per hour) at sea level.
• Supersonic speeds are described by their "Mach number".
• Mach number: The ratio of the speed of the object to the speed of sound in the air of the same temperature and density is called Mach number.
  • Supersonic includes speeds up to five times faster than the speed of sound, or Mach 5.

EXPLANATION:

• When the speed of any object exceeds the speed of sound, it is said to be traveling at Supersonic speed. So option 2 is correct.

EXTRA POINTS:

• Subsonic has a speed of less than 0.8 Mach.
• Hypersonic may have a speed between 5-10 Mach.

According to the question:

Since 7 is the part of the men as well as the women.

So, 7 men are women.

Hence, 7 is the correct answer. 

Note: If in the question asked "how many men are only women", then the answer, in this case, would be 0.

The correct answer is option 2 i.e C₄H_10.

Concept:

Hydrocarbons

• Compounds made of carbon and hydrogen atoms only are called hydrocarbons.
• Saturated hydrocarbons:
  • The hydrocarbons in which carbon atoms are singly bonded are called saturated hydrocarbons.
  • Saturated hydrocarbons are also called alkanes or paraffin.
    • The general formula of alkane– CnH2n+2.
• Unsaturated hydrocarbons:
  • The hydrocarbons in which carbon atoms are either doubly or triply bonded are called unsaturated hydrocarbons.
  • Doubly bonded (carbon atoms) hydrocarbons are called alkenes.
  • The general formula of alkene is CnH2n.

• The formula for alkane should be mentioned C_nH_2n+2

Explanation:

Given code language:

'nee muk pic' means 'grave and concern';
'ill dic so' means 'every body else'; and
'tur muk so' means 'body and soul'.

So we can decode the following words:

muk - and

so' - body

'tur - soul

Proceeding ahead accordingly, the code for 'every' is either 'ill' or 'dic' and the code for 'concern' is either 'nee' or 'pic'.

The correct answer is Basketball.
