Answer:
A = 120
B = 40
C = 70
Solution:
As per the question:
Manufacturer forced to make 10 more type C clamps than the total of A and b:
10 + A + B = C                (1)
Also, 3 times as many type B as type A clamps are:
A = 3B                             (2)
The total no. of clamps produced per day:
A + B + C  = 330              (3)
The no. of each type manufactured per day:
Now, from eqn (1), and (3):
A + B + 10 + A + B = 330 
2A + 2B = 320
A + B = 160                       (4)
Now, from eqn (2) and (4):
3B + B = 160
B = 40
Since, A = 3B
A = 
A = 120          
Put the values of A and C in eqn (3):
120 + 40 + C = 330
C = 70
