Answer 1

To calculate the standard consistency of cement, you use the following formula:

Standard Consistency(%)=(Water added (in ml)Weight of cement (in g))×100\text{Standard Consistency} (\%) = \left( \frac{\text{Water added (in ml)}}{\text{Weight of cement (in g)}} \right) \times 100Standard Consistency(%)=(Weight of cement (in g)Water added (in ml)​)×100

Given:

• Water added = 100 ml
• Cement weight = 1000 g

Now, applying the formula:

Standard Consistency(%)=(1001000)×100=10%\text{Standard Consistency} (\%) = \left( \frac{100}{1000} \right) \times 100 = 10\%Standard Consistency(%)=(1000100​)×100=10%

So, the correct answer is:

(a) 10
