- How many marks did he get .
<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>
Let us say that the maximum marks for the exam was x . So he got 75% of x that is ,
Marks = 75% of x
Marks = 75/100 × x
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>

3b+5r=2 gallons of cabbage red
1r+7b=2gallons of egplant
1 gallon of cabbage sells for 22 (means 2 gallos is 44)
1 gallon of egplant is 26 (means 2 gallons is 52)
3b+5r=44
r+7b=52
r+7b=52
miinus 7b from both sides
r=52-7b
sub 52-7b for r in othe equestion
3b+5(52-7b)=44
3b+260-35b=44
-32b+260=44
minus 260 from both sides
-32b=-216
divide both sides by -32
b=6.75
r=52-7b
r=52-7(6.75)
r=52-47.25
r=4.75
3blue+5r=2gallons
5+3=8
8units=2gallons
4units=1gallon
1unit=1quart
therefor
1 quart of blue paint is $6.75
1 quart of red paint is $4.75
