How to solve this?

Since it is a binary ladder type DAC

V = (16 + 8 + 2/2^5) * 10.
= 8.125V.

Given that;

5- bit ladder D/A converter= 2^5,
Digital input= 11010.
Then,

11010= 1*2^4+1*2^3+0*2^2+1*2^1+0*2^0,
= 16+8+0+2+0,
=26.

V= 10v
Since, it is binary ladder type DAC
So,
V(output)= (16+8+2/2^5)*10
= 8.125v
That's all.

Input voltage =2^5 = 32
V = 11010 puts 1=10v or 11010=26*10v = 260v,
V = 16*10+8*10+0*10+2*10+0*10 = 260v,
Output voltage= 260/32 = 8.125v.
