Question Discussion & Solution

People – A, B, C, D, E and F

All are facing north.

1. C is sitting 2^nd to the left of D.

2. Only two person sits between A and B.

3. E is sitting at the extreme left end and neither F nor A is the immediate neighbour of E.

4. B is sitting to the left of A.

As, F and A are not the immediate neighbours of E, Case I is eliminated and the arrangement with the combination of Case II, thus formed is:

Hence, D is at the extreme right end.

CONCEPT:

• The battery has two terminals positive and negative and its positive terminal is the cathode and its negative terminal is the anode.
  • It works on the principle of Electrochemical Reaction.
  • Italian physicist Alessandro Volta built and described the first electrochemical battery, the voltaic pile, in the year 1800.
  • The lead-acid batteries used in vehicles and lithium-ion batteries used for portable electronics such as laptops and mobile phones.

EXPLANATION:

• A battery converts chemical energy into electrical energy. So option 3 is correct.

Here the coding is,

So, the coding for SOUP is,

The numbers are "2".

Hence, there are one such numbers.
