(Q8)Percentage of nitre=60%
Percentage of sulphur=25℅
Percentage of carbon=
(100-60-25)℅=15℅
Quantity of gun powder=48 grams
Quantity of nitre= 60℅ of 48grams
60/100×48=28.8grams
Quantity of carbon=
15℅ of 48 grams
15/100× 48grams=7.2 grams

(Q9)Marks got=325
Difference of passing marks and marks got=35
Passing Marks=325+35=360
According to the question passing marks are 40℅
Let the total marks be x
40℅ of x= 360
40x/100=360
40x=36000
x=36000/40
x=900
So the total marks are 900

(Q10)Total Money=Rs.150000
Share of first person= 32℅of Rs. 150000
32/100×150000
32×1500=Rs.48000

Share of second person=
35℅ of 150000
35/100×150000
35×1500=Rs.52500

Shade of third person=
(100-32-35)% of 150000
33℅ of 150000
33/100×150000
33×1500=Rs.49500
