Sending survey questions to the particular percentage of participants

In the directory or your database, you can add a column with values like 100, 75, and 25 so that they are recorded as embedded data. Then, using logic, you can configure which questions are shown to participants.

maybe you can set up two randomizers in your survey flow at the top.

One randomizer (for 75%) with 3 embedded data 2Question = Yes and 1 embedded data 2Question = No and evenly presented 1 element. 

The other randomizer (for 25%) 1 embedded data 3Question = Yes and 3 embedded data 3Question = No and evenly presented 1 element.

Then, set the display logic of the 2 questions to appear based on the embedded data 2Question= Yes and set the display logic of the 3 questions to appear based on the embedded data 3Question= Yes.

Hello ​@Phani -

You can take help of quotas if you know which questions should be shown to 75% of respondents and which question should be shown to 25% of respondents.

I will create 3 separate blocks  -
Block 1 -  for 5 question which will be shown to all
Block 2 -  for 2 question which will be shown to 75% of total respondents
Block 3 -  for 3 question which will be shown to 25% of total respondents

Once 3 blocks are created in survey builder. Go to survey flow.
In survey flow ​​​​​​​create ED below Block 1 - eg - Answered Block 1 and assign it 1
                          create ED below Block 2 - eg - Answered Block 2 and assign it 1
               same create ED below Block 3 - eg. - Answered Block 3 and assign it 1

Then go to quotas page - select cross logic quota
If aim for me is to collect 100 responses - my total quota will be set to 100.

Then add logic in quotas as shown in screen shot below. 

Once quotas are made again go back to survey flow.

above block 2 add a branch - if quota for Answered Block 2 equal to 1 is not met 
same above block 3 add a branch - if quota for Answered Block 3 equal to 1 is not met 

added SS for this as well for clear reference.

SO if you have 100 respondents Block 1 will be displayed to 100 respondents, Block 2 will be displayed to 75 participants and block 3 will be displayed to 25 participants as each of the blocks quota will be full. If you change the total quota, percentage in distribution is dynamic and will take care of distributing as set by us.
