Answer Posted / aamir shahzad
ratio is 1:2:4 sum is equle 7
1 bag cement is equle to 1.25
total quantity resum is 200 cft
dry Volume of total quantity which is 200 cft to multiply
1.54 will be the value of total quantity is 308 cft.
which is the total quantity 308 multiply 1(which is cement
ratio)and divided 7 which is the sum of ratio it will
become 44 and now we convert cft to cement bag which is the
value of 1.25 for bag.
44 divided by 1.25 is 35.2 the Sum is 35.2 Cement of Bags.
same for sand. which value was came after dry
308 multiply ratio of sand which is 2 then divided sum of
the ratio which is 7 will become the value of Sand is=88 cft
for crash 308 multiply 4 which is the value of crush and
devided by sum of value which is 7 total sum will become
176 cft.
Total sum of quantity of 1:2:4 mean.
Cement=35.2 Bags
Sand= 88 cft
Crush= 176 cft
These are right answer.
