What is the population of females in the town? (A) 7000 (B) 6000 (C) 6400 (D) 5800 (E) 5600 The population of a village is 6400. Let M = the ORIGINAL number of males in the village Let F= the ORIGINAL number of females in the village So, we can write: M + F = 6400 If the number of males increased by 40% and that of females increased by 30%, the population becomes 8380. So, 1.4M = the RESULTING number of males And 1.3F = the RESULTING number of females So, we can write: 1.4M + 1.3F = 8380 What is the population of females in the town? We now have the following system of equations: M + F = 6400 1.4M + 1.3F = 8380 Take the top equation, and multiply both sides by 1.4 to get the following equivalent equation: 1.4M + 1.4F = 8960 1.4M + 1.3F = 8380 Now subtract at the bottom equation from the top equation to get: 0.1F = 580 Solve: F = 580/0.1 = 5800 Answer: D _________________ Brent Hanneson – Creator o...
[SOLVED] The total number of male population in both villages is what perc
The total number of male population in both villages is what perc Directions: Read the passage carefully and answer the questions accordingly. In village A, there are 40% females. The number of males in Village B is double of the number of males in village A. The number of males and females in village B is equal. Question 1: The total number of male population in both villages is what percent more or less than the total number of female population in both villages? SOLUTION Given:Percentage of male in village A = 60% Percentage of female in village A= 40% Numberof male in village B= 2× Numberof male in village A Numberof female in village B =Numberof male in village B Calculation: Let total population of village A be x. Numberof male in village A = 60% of x = 0.6x Numberof female in village A= 40% of x = 0.4x Numberof male in village B= 2× 0.6x = 1.2x Numberof female in village B = 1.2x Total number of male population of both village = 0.6x + 1.2x = 1.8x Total number of female population of both village = 0.4x + 1.2x = 1.6x ∴ Desired percentage = (1.8x - 1.6x)/1.6x× 100 = 12.5%

hafiz ulla Let no. of men be x and no. of women be 5000 - x Population increased from 5000 to 5600 i.e. 600 men increased % = 10% of x And women increased % = 15% of (5000 - x) so, 10% x + 15%(5000 - x) = 600 10/100 + 15/100(5000 - x) =600 10x + 75000 - 15x = 60000 -5x = -15000 x = 3000 So, the no. of males = 3000.
