35%
50%
65%
none of these.

By interpolation with 25 we get the correct answer as 61.67.

Maharshi Saxena said:   7 years ago
The correct Answer is 50%.

Yadav said:   7 years ago
Yes, the Correct answer is 50%.

LL= water content at 20 blow.
100-10/20-70= 100-20/20-LL,
LL= 64.44.

You cannot use interpolation because it is semilog graph.

Liquid limit WL is the one which is the water content at 25th blow. So simply interpolation is applied as;

Log 10 -> 0.7
Log 25 -> ?
Log 100 -> 0.2.

So I got answer 0.5....i.e. 50%.
Is that right?

50.10 is correct and one point method is not applicable because it is valid for 20 to30 blows not for 100 blows.

65% is the right answer. Just draw the flow curve graph roughly. You will get it easily.

Kranthi said:   8 years ago
50% is correct.

Ashu said:   8 years ago
It is 61%.
