Question Discussion & Solution

1) H 12D → H = 8; D = 4; hence 8 + 4 = 12

2) A5D → A = 1; D = 4; hence 1 + 4 = 5

3) C16L → C = 3; L = 12; hence 3 + 12 = 15 which is not equal to 16.

4) I22M → ​ I = 9; M = 13; hence 9 + 13 = 22.

Hence C16L is the odd one out.

• A CASE tool is a generic term used to denote any form of automated support for software engineering, in a more restrictive sense a CASE tool can mean any tool used to automate some activity associated with software development
• Some of the CASE tools assist in phase-related tasks such as specification, structured analysis, design, coding, testing, etc. and others to non-phase activities such as project management and configuration management
• The primary objectives of using any CASE tool are:

1. To increase productivity.
2. To help produce better quality software at a lower cost.

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.
