@All.
W/c * cement = 0.3 * cement + 0.1 * fine aggregate + 0.01 * coarse aggregate.
0.6 * C = 0.3 * C + 0.1 * 50 + 0.01 * 100.
C = 20KG.
W/C * Cement = wt of water.
= 0.6 * 20 = 12 kg.
W/c * cement = 0.3 * cement + 0.1 * fine aggregate + 0.01 * coarse aggregate.
0.6 * C = 0.3 * C + 0.1 * 50 + 0.01 * 100.
C = 20KG.
W/C * Cement = wt of water.
= 0.6 * 20 = 12 kg.

We have the relation of:
0.3 * cement + 0.1 * sand + 0.01 * aggregate = w/c * cement.
Here,
0.3 * c + 0.1 * 50 +100 * 0.1 = 0.6 * c.
c = 20 kg.
w/c = 0.6.
So, water = 0.6 * 20 = 12 kg.
0.3 * cement + 0.1 * sand + 0.01 * aggregate = w/c * cement.
Here,
0.3 * c + 0.1 * 50 +100 * 0.1 = 0.6 * c.
c = 20 kg.
w/c = 0.6.
So, water = 0.6 * 20 = 12 kg.

W/C * P = 0.3P + 0.1F.A +.01C.A.
0.6 * P = 0.3P + 0.1(50) + 0.01(100),
0.6P - 0.3P = 5 + 1,
P = 6/0.3.
P = 20 => Where P= Cement.
Now;
W/C = 0.6,
W = C * 0.6,
W = 20 * 0.6,
W = 12Kg.
0.6 * P = 0.3P + 0.1(50) + 0.01(100),
0.6P - 0.3P = 5 + 1,
P = 6/0.3.
P = 20 => Where P= Cement.
Now;
W/C = 0.6,
W = C * 0.6,
W = 20 * 0.6,
W = 12Kg.

Here 50 kg weight of cement:
M 25 ratio 1:1:2.
(5% weight of aggregate + 30 weight of cement)w/c ratio.
M 25 ratio 1:1:2.
(5% weight of aggregate + 30 weight of cement)w/c ratio.

In harsh mix weight of water =. 30% wt of fine aggregate + .05% wt of coarse aggregate) water-cement ratio.

Where does this formula comes from?
W/C *P = 0.3P + 0.1F.A +.01C.A
How do you justify it? Please explain me.
W/C *P = 0.3P + 0.1F.A +.01C.A
How do you justify it? Please explain me.

Wt. Of water = (5% of Coarse aggregate + 30% of fine aggregate) * water cement ratio.
Therefore,
Wt. Of water = {5 * 100/100 +30 * 50/100} * 0.6,
Wt. Of water= 12kg.
Therefore,
Wt. Of water = {5 * 100/100 +30 * 50/100} * 0.6,
Wt. Of water= 12kg.
