50.10 is the correct answer.
It is not a triangle so don't use similar triangles. it is a logarithmic function. interpolate it using ln.

@Pratima Yadav.
The formula you put is right but followed that formula we supposed to get 39 (62.56-23.56) this option was not given.

Just interpolate it on semi log graph paper. i.e No.of blows on logarithmic x-axis and m.c on y-axis and then find LL along 25 blows.

The arbitrary limit of water content that represents the boundary between the liquid & plastic state is called as liquid limit.

By interpolation, we can find the liquid limit corresponding 25 no of blows do not for the gate to take no of blows on lag scale.

@Aakash karoo.
Your simple steps helped me get the right answer which is 65%, the graph part is actually much easier!
Thanks.

Water content at 25 blows gives you the liquid limit.
Just interpolate the given values for 25 blows. You get the answer as 65.

70% correspond.
Linear rules:- 70-(((70-20)/(10-100))*(10-25)),
=70-8.33,
= 62.67.

The formula of liquid limit =w* (N/25) ^0.121.
Find, LL for each condition and then subtract them. You will get 65% as answer.

If we use flow index than the answer coming is 50. And plot shall be along log scale wouldn't rough idea from that be wrong?
