A salesman used three types of order forms: A, B, C. He used 40 of Form A. Of Form B he used four times as many as Form A plus 1
mixas84 [53]

Answer:

The correct option is A. 440

Step-by-step explanation:

Let a, b and c represents the number of orders from forms A, B and C,

According to the question,

a = 40,

b = 4a + \frac{1}{2}c

c = a + \frac{1}{2}c

From these equations we get,

b = 160 + \frac{1}{2}c----(1)

c = 40 + \frac{1}{2}b---(2)

Substitute the value of b from (1) to (2),

c = 40 + \frac{1}{2}(160 + \frac{1}{2}c)

c = 40 + 80 + \frac{1}{4}c

c-\frac{1}{4}c = 120

\frac{4c-c}{4}=120

\frac{3c}{4}=120

c=\frac{480}{3}=160

From (1),

b = 160 + \frac{1}{2}(160)=160 + 80 = 240

\because a + b + c = 40 + 240 + 160 = 440

Hence, he used 440 forms total,

i.e. OPTION A is correct.
