Maria and Sheila total marks are illustrations of proportions
The total marks obtained by both is 156
<h3>How to determine their total marks?</h3>
The given parameters are:
Sheila = 96 marks
2/5 of Maria's marks = 1/4 of Sheila's marks
The second highlight above means that:
2/5 * Maria = 1/4 * 96
Multiply both sides by 5/2
Maria = 1/4 * 96 * 5/2
Evaluate the product
Maria = 60
Their total mark is then calculated as:
Total = Sheila + Mark
This gives
Total = 96 + 60
Evaluate the sum
Total = 156
Hence, the total marks obtained by both is 156
