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

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

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?
Log 10 -> 0.7
Log 25 -> ?
Log 100 -> 0.2.
So I got answer 0.5....i.e. 50%.
Is that right?

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

The correct Answer is 50%.

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

Liquid limit(1)=70*(100÷25)^.121=82.78.
Liquid limit (2)=20*(10÷25)^.121=17.90.
Total =82.78-17.90 =64.88%.
Say 65%.

L.L = 70%-50%(0.4) = 50%.
