Alfred's garage has some metal rod's of lengths, 10 cm, 20 cm, 50 cm and 1 m.

25% of the them are 50 cm in length.

The number of 20 cm rods is `3/5` of the number of 50 cm rods.

The ratio of the number of 10 cm rods to the number of 20 cm rods is 4:3.

The remaining rods are 1 m in length.

The number of 1 m rods is 60 less than the combined number of all the other rods.
