The following table gives the percentage (%) of people having knowledge of different programming languages. The total number of people having knowledge about programming languages is 12,00,000.Programming language % of People having knowledge C++ 15% C 25% COBOL 12% FORTRAN 13% Java 15% LISP 10% Python 10%
Difference in the number of people having knowledge of C and COBOL programming language is
1,56,000
To solve the problem of finding the difference in the number of people having knowledge of C and COBOL programming languages, we will follow these steps:
- Calculate the total number of people who know C.
- Calculate the total number of people who know COBOL.
- Find the difference between these two values.
Let's break down each step:
- Number of people who know C:
\(= \left(\frac{25}{100}\right) \times 12,00,000\)
\(= 3,00,000\) - Number of people who know COBOL:
\(= \left(\frac{12}{100}\right) \times 12,00,000\)
\(= 1,44,000\) - Difference in the number of people:
\(= 3,00,000 - 1,44,000\)
\(= 1,56,000\)
Therefore, the difference in the number of people having knowledge of the C and COBOL programming languages is 1,56,000.
Thus, the correct answer is:
- 1,56,000
