The prices of seven mobiles M1, M2, M3, M4, M5, M6 and M7 are compared. The price of M7 is more than M5 and less than M4. The price of M1 more than M6 and less than M2. The price of M2 is less than the price of M5. If the price of M4 is less than only one mobile, then which of the following options is correct?

M3 > M4

1) The price of M7 is more than M5 and less than M4

 M4> M7> M5

2) The price of M1 is more than M6 and less than M2

 M2> M1> M6

3) The price of M2 is less than the price of M5

 M5> M2

4) if the price of M4 is less than only one mobile

 M3> M4

So the actual order is;

 M3> M4> M7> M5> M2> M1> M6> M5> M2

Therefore,  M3> M4 is correct
