A) 15
B) 13
C) 12
D) 11
Correct Answer: D
Solution :
[d] As \[0<x<1,\] we have \[p<q\] The number of rational numbers \[=5+4+3+2+1=15.\] When p, q have a common factor, we get some rational numbers which are not different from those already counted. There are 4 such numbers: \[\frac{2}{4},\frac{2}{6},\frac{3}{6},\frac{4}{6}\] Therefore, required number of rational numbers \[=15-4=11.\]You need to login to perform this action.
