Question

shweta got 86% marks in the annual examination if she got 645 marks in all,find the total numbers of marks of the examination​

Answer 1

Answer:

750 marks.

Step-by-step explanation:

If $645$ marks are 86% of total marks, then, we will divide 645 by 86:

$\frac{645}{86}$ = 7.5. So, in this scenario, 7.5 marks are 1% of total marks. Now we will multiply 7.5 * 100 to find the total 100%. So it will be: 7.5 * 100 = 750.

Answer: 100% will be 750 marks.

$=750$ marks
