<u>Given</u><u> </u><u>:</u><u>-</u>
- John scored 75% of the total marks .
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
- How many marks did he get .

Marks = 3/4 × x
Marks = 3x/4
<u>Hence</u><u> </u><u>he </u><u>s</u><u>cored </u><u>3x</u><u>/</u><u>4</u><u> </u><u>marks </u><u>in </u><u>the</u><u> </u><u>test.</u>
