To solve this one, you need to work out how the five images below are connected.
Once you have worked out the link, you will be able to deduce the full name associated with each.
Allocate the 5 letters F to J with these where:
F=the name associated with image A
G=the name associated with image B
... and so on...
NOTE: For clarification, though you do need to identify who the individuals are in the images A-E, the name you are seeking for 'F' is NOT the name of the person in image 'A'. This holds true for each of the names F-J. All will become clear once you have cracked it.
And, once you have indeed worked it all out :
K=the number of letters in the name of person F (two names, first and last).
L=the number of letters in the name of person G (two names).
M=the number of letters in the name of person H (two names).
N=the number of letters in the name of person I (two names).
O=the number of letters in the name of person J (three names).
P=the number of letters in the name given to the group of individuals F-J (three words).

Where Y = (((K x (P - L)) + M) x O) + N and Z = ((O + L) x (P + K)) - M
