An electronic salesperson carries 6 identical amplifier tubes, 5 identical rectifiers, 2 identical condensers, and 4 identical relays. in how many different ways can these parts be arranged in a row?

The number of ways of arranging these items in a row is:

                            85,765,680

It is given that:

An electronic salesperson carries 6 identical amplifier tubes, 5 identical rectifiers, 2 identical condensers, and 4 identical relays.

Hence, the total number of items are:

17 ( since 6+5+2+4=17)

Hence, the number of ways it could be arranged in a row is calculated as:

which on solving gives us: 85,765,680

Hence, the number of ways of doing so is:

                              85,765,680
