Importance of Indirect Proportion
Indirect proportion is very useful for solving logical reasoning problems in real life and in higher education level . In UGC NET has also included it in logical reasoning .
I can explain its importance with simple example
If 4 women can reap a field in 10 days, how long will 5 women take to reap it .
we can solve above problem with the rule of indirect proportion by following way
4 X 10 = 5 X x
4 X 10 / 5 = x
8 = x
5 women can reap it in 8 days .
If increase of women's number , it will decrease the number of days , so the rule of indirect proportion will apply
