This is our Learn Programming through Logical Thinking Series – 2. Here we are going to discuss about one more puzzle or aptitude. The question looks as follows:
Aptitude:
A can do a certain job in 12 days. B is 60% more efficient than A. How many days does B alone take to do the same job?
Answer:
Ratio of time taken by A and B = 12 days and x days .
The efficiency of A and B will be in the ratio 100 : 160 = 5 : 8
Now, if we calculate the indirect proportion method – it would be
5 : 8 = 12 : x
8 x = 5 * 12
X = 7.5 days
So B takes only 7 and half days to complete the entire work .
Algorithm:
1.Get A’s total work in days from user.
2.Then A’s work is multiply by 5. MultiplyValue= A’s work*5
3.Calculate B’s working days by MultiplyValue is divided by 8.
4.Print B’s working days.
5.Stop.
Now, shall we try to solve the same problem through a Java Program? It is quite simple. As this is my first puzzle to solve, I have given my class name here as MyAppti1.
public class MyAppti1 {
public static void main(String[] args) {
doubleMultiplyValue,DividedValue,work=12;
MultiplyValue = work * 5;
DividedValue = MultiplyValue / 8;
System.out.println(“B’s work is” +DividedValue);
}
}
