Answer 2

Answer:

4000

Step-by-step explanation:

step 1;

total population = 12000

but survey taken only upti 150 members.

so we should consider the ratio of these two = 150/12000 = 1/80.

step 2;

atleast 2 programs so add (16+24+10) =50 according to veen diagram.

so these 50 people are in 150 of those were taken survey.

Compare the 50 people according to ratio in step 1 (1/80).

so here 1 part is equal to 50 people then 80 is equal to 4000.

Ans: 4000.
