Let there be 'a' bottles in each row.
number of rows=a
 
so number of bottles are = a2
It is given that after arranging bottles in the form of square,16 were left over
Total number of bottles = a2 + 16But total number of bottles are 160

then    a2 +16  =160 a2 = 160 - 16 a2 = 144 a = 12 There were 12 bottles in each row.
