Calculate the student's percentage if she scored 43 out of 50 according to the rule below

Each semester test is out of 50. You need to work each out to be a percentage. Then multiply each test's percentage with 0.3 (30%) as each test contributes 30% towards your final mark.

To calculate the student's percentage based on scoring 43 out of 50:

Step 1:
Calculate the percentage for the test:
(43/50) x 100 = 86%

Step 2:
Multiply the test percentage by 0.3 (30%):
86% x 0.3 = 25.8%

Therefore, the student's percentage for this test is 25.8%.
