Answer:

2 wrongly solutions and 18 right solutions

Step-by-step explanation:

The computation is shown below:

= 20 (problems) × 10 (points)

= 200 points

And it received 176 points

So the difference is of

= 200 - 176

= 24

In the case of wrong solution, the points that are lost is

=  10 + 2

= 12

Now the solutions done wrongly is

= 24 ÷ 12

= 2

And, the solutions does rightly is

= 20 - 2

= 18
