The ages of seven girls G1, G2, G3, G4, G5, G6 and G7 are compared. No two girls have the same age. The age of G3 is less than only two girls. The age of G1 is greater than G4 and G7. The age of G6 is the lowest. The age of G5 is not the highest and it is greater than G1. The age of how many girls is greater than G5?

1

There are 07 girls

1) The age of G1 is greater than G4 and G7

 G4, G7 < G1

2) The age of G5 is not the highest and it is greater than G1

 G1 < G5

3) The ae of G3 is less than only two girls

 G3 <_ <_

4) The age of G6 is the lowest

 G6<_ <_ G1< G3< G5< G2

5) No two girls have the same age

Thus, we have two possibilities here;

 (i) G6< G4< G7< G1< G3< G5< G2

 (ii) G6< G7< G4< G1< G3< G5< G2

Therefore, only one girl is grater than G5
