I think the number of computers should be same. We should treat S(2) as independent of S(1).

Harshk2903
Logically the no. of sales persons in given time should be same. Any comments on that?

A computer dealership has a number of computers to be sold by its sales persons. How many computers are up for the sale?

(1) If each of the sales persons sells 5 of the computers, 18 computers will remain in stock.
(2) If each of the sales persons sells 4 of the computers, 28 computers will remain in stock.

Statement 1: Total computers be X and number of Salesman be Y
X=5Y+18

Statment 2:
X=4Y+28

Each statement alone is not sufficient, Together we have
5Y+18=4Y+28
Y=10
X=68 computers
C is the answer.

how many computers up for sale :
Option 1:
If each of the sales persons sells 5 of the computers, 18 computers will remain in stock
can't say anything conclusive, it can be any number. Not sufficient

Option 2:
If each of the sales persons sells 4 of the computers, 28 computers will remain in stock
so here also it can be any number Not sufficient.

Option 1+2
Let x be the number of sales person then total computers can be equated as
5x+18 =4x+28
x=10
So total computers are 68. Hence both options together sufficient

(2) If each of the sales persons sells 4 of the computers, 28 computers will remain in stock.

Essentially, the solutions above getting C are correct. Both statements refer to the same number of salespersons and the same number of computers. So we get 5x + 18 = 4x + 28. Solving this gives x = 10 (the number of salespersons), and subsequently the number of computers is 68.
