Answer 1

Step-by-step explanation:

Given Brindha secures 85%, 86% and 84% marks in the test papers with 100, 150 and 200 respectively as maximum marks.  

• Given Marks scored out of 100 ,150 and 200 by Brindha is 85% , 86% and 84%. These are maximum marks obtained by Brindha.  
• Now we need to find the percentage of Brindha’s aggregate.
• So we get 85 / 100 x 100 = 85
•                86 / 100 x 150 = 12,900 / 100 = 129
•                84 / 100 x 200 = 16800 / 100 = 168
•                  = 84 + 129 + 168 = 382
• Also 100 + 150 + 200 = 450
• Therefore aggregate will be 382 / 450 = 0.8488
• Therefore aggregate percentage will be 0.8488 x 100 = 84.88%
