Question 1090142
1.2  3(x-15)=54; 3x-45=54; 
1.3 log (x+10)=2; raise everything to the 10th power x+10=100, x=90
Regarding 2.
This to me is unclear
50% interviewed are youth
33% are living with disability
20% of the remainder (that would be 1/5 of 1/6 or 1/30) are pensioners, and the remaining 2500 villagers did not take part in the survey. Since I don't have any guide to the number of people who were interviewed, only the results, nor the relationship between the number interviewed and the number not interviewed, I can't go further.
disability and pensioners I can do the fraction and the numbers for both are above.  To get the total number of people living in the village, I need the information mentioned above. One number for say the youth would give me the number surveyed.
