Answer 1

Hint: Here in this question, we have to find the total persons present in the park. To solve this, ready the question carefully and by analysing each sentence write the number of different category peoples and next summing all the peoples of different categories by using an addition operation we get the required solution.

Complete step-by-step answer:
Consider the question,
Read the question carefully and write the given information one by one:
I was sitting alone in a park, which means I have one person sitting in the park. After some time or a while there came an old man and an old lady, i.e., two people. After the old age peoples followed by the two couples each couples having 2 persons which means 2 couples having 4 persons, the couples accompanied by a child each means each couple having 2 child’s then 2 couples having 4 children.
The total number of persons present in park is:
I am the one person = \[1\]
Old man and lady = \[2\]
2 couples = \[2 + 2 = 4\]
Accompanied by a child each = \[1 \times 2 + 1 \times 2 = 4\]
Total number of persons present in park is:
\[ \Rightarrow \,\,\,1 + 2 + 4 + 4\]
\[ \Rightarrow \,\,\,11\]
Hence, 11 persons are there in the park.
Therefore, option (C) is correct.
So, the correct answer is “Option C”.

Note: To solve this kind of problem, we have to read the sentence carefully. They have mentioned a couple; it means 2 people are there. Some words will represent the kind of number. For example: pair, couple etc., The word accompanied by a child each means one child has a company of another child. The sentences will be twisty.
