Answer 1

Answer:

c)40% is the correct ans

Answer 2

Concept:

In order to have as few implementation dependencies as feasible, Java is a high-level, class-based, object-oriented programming language. It is a general-purpose programming language designed to enable programmers to write code once and have it run anywhere (WORA).

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means.

Given:

In a certain department, 60% of the department is female and the rest are males, if 15% of

the females and 25% of the males are working on a Java project,

Find:

Percentage of people working in the java project

Solution:

Let there be 100 people in the department

So, no. of males will be 40

No. of females will be 60

No. of females working on java project=15% of 60

                                                                 =15/100 x 60

                                                                 =9

No. of females working on java project=25% of 40

                                                                 =25/100x40

                                                                 =10

Total no. of people working in the java project=10+9

                                                                             =19

So percentage of people working in java project= 19x 100/100

                                                                                  =19%

Therefore,percentage of people working in java project =19%
