Statement (1)
Statement (2)
Combining both statements (1) and (2)
Let the sales in 1980 be S.
From statement (1):
S+2,500,000=2S
S = 2,500,000
Hence, sales in 1980 were $2,500,000 and sales in 1990 were $5,000,000
Both statements combined are sufficient to find the 1990 sales value. Individually, each is insufficient.
- Sales increased by $250,000 each year from 1980 to 1990.
Statement (2)
- Sales doubled between 1980 and 1990.
Combining both statements (1) and (2)
Let the sales in 1980 be S.
From statement (1):
- Sales increase each year by $250,000 for 10 years, so total increase over 10 years = 10×250,000=2,500,000.
- Sales in 1990 =S+2,500,000.
- Sales in 1990 =2S
S+2,500,000=2S
S = 2,500,000
Hence, sales in 1980 were $2,500,000 and sales in 1990 were $5,000,000
Both statements combined are sufficient to find the 1990 sales value. Individually, each is insufficient.

Let the values of sales in 1980 and 1990 are x and y respectively.
We need to find y?
Statement 1:
(1) The sales of Pioneer Computers increased by $250,000 each year from 1980 - 1990
The increase each year is $250000.
In 1980 , its x
In 1990, y = x + 10*(250,000) = x + $2,500,000.
Without knowing the value of x and y, we cannot find anything conclusive.
Hence, Insufficient.
Statement 2:
(2) The value of the sales of Pioneer Computers doubled between 1980 and 1990
1980 = x
1990 = y = 2x
Without, knowing the value of x, we cannot find it.
Hence, Insufficient.
Combining both statements , we get
y = x + 10*(250,000) = x + $2,500,000.
2x = x + $2,500,000
x = $2,500,000
Then, y = 2x = 2* $2,500,000 = $5,000,000.
Hence, Sufficient
