A) Prime numbers are like 2, 3, 5, 7, etc.
97 is prime and 2 is prime but most books do not consider 1 prime or composite, it is just special.

Answer : 31 + 67 + 2


C)if we change B, C, D to the form of A then

A = A
B = A/2
C = 2A/6
D = 6A/4

eq : A + A/2 + 2A/6 + 6A/4 = 125

THEN A IS 60

and if A is 60 then B(A/2) is 30, C(2A/6) is 20 and D(6A/4) is 15.
