Answer:
1. $82,500
2. 169 : 110
Explanation:
The computation is shown below:
Given that 
1. Ratio between two computers is 3:2
And the first computer cost is $55,000
Let us assume the price of the second computer be x. 
As we know that 
 Product of extremes = Product of mean. 
2 : 3 :: 55000 : x .
Now cross mutiplication is to be done 
 2x = $55,000 × 3 
 x = $1,650,000 ÷ 2 
 = $82,500
2. Now if the price of the 2nd computer rised by $2,000
So the new cost would be 
= $82,500 + $2,000
= $84,500
Now the ratio would be 
= $55,000 : $84,500
= 169: 110
