Given :- The total population of a village is 6000 . the number of males and females increases by 10% and 20% respectively and consequently the population of the village becomes 7500 . what was the number of males in the village ?
Answer :-
Let number of males are x . so, females are (6000 - x) .
A/q,
→ 10% of x + 20% of (6000 - x) = 7500 - 6000
→ (10 * x)/100 + 20 * (6000 - x)/100 = 1500
→ (10x + 20*6000 - 20x) / 100 = 1500
→ 120000 - 10x = 150000
→ 10x = 120000 - 15000
→ 10x = (-30000)
→ x = (-3000)
Data of the question is wrong .
if we take popultion becomes 7000 ,
then,
→ 10% of x + 20% of (6000 - x) = 7000 - 6000
→ (10 * x)/100 + 20 * (6000 - x)/100 = 1000
→ (10x + 20*6000 - 20x) / 100 = 1000
→ 120000 - 10x = 100000
→ 10x = 120000 - 100000
→ 10x = 20000
→ x = 2000 (Ans.)
