Solution

The problem involves a ratio of appeared to successful students, which is 7:3. This means that for every 7 students that appeared, 3 were successful.

First, we need to find out how many '7 student' groups there are in 343. We do this by dividing 343 by 7, which equals 49.

Since we know that 3 students are successful for every group of 7, we then multiply 49 (the number of '7 student' groups) by 3 to find out how many students were successful.

49 * 3 = 147

So, 147 students got through the test.
