Question Discussion & Solution

Here the pattern is,

0.15552 ÷ 0.3 = 0.5184,

0.5184 ÷ 0.3 = 1.728,

1.728 ÷ 0.3 = 5.76,

Similarly, we have :

5.76 ÷ 0.3 = 19.2

Concept:

The GROUP BY statement groups rows that have the same values into summary rows, like "find the number of customers in each country".

The GROUP BY statement is often used with aggregate functions (COUNT, MAX, MIN, SUM, AVG) to group the result-set by one or more columns.

GROUP BY Syntax

SELECT column_name(s)
FROM table_name
WHERE condition
GROUP BY column_name(s)
ORDER BY column_name(s);

The ORDER BY keyword is used to sort the result-set in ascending or descending order.

The ORDER BY keyword sorts the records in ascending order by default. To sort the records in descending order, use the DESC keyword.

ORDER BY Syntax

SELECT column1, column2, ...
FROM table_name
ORDER BY column1, column2, ... ASC|DESC;

Statement: Should electric two wheelers be subsidized?

Argument:

I. Yes, Should electric two-wheelers be subsidized because electric two-wheelers do NOT create pollution. It prevents our country from pollutions and diseases related to pollution. Therefore, Argument I is strong.

II. Charging takes much longer than filling petrol. It means the charging process takes more time to charge and also consumes more electrical power and more time taking in comparison to petrol filling, but its cost is less than petrol. So, Argument II is not strong.

Here, we can say " Only Argument I is Strong".

Hence, "Only Argument I is Strong" is correct answer.
