In 2015, the ratio of populations of villages A, B and C are in ratio 3:2:5 respectively and the total number of illiterate people in all the villages together are 700. What is the population of village C in 2015?

Correct

Answer- 2) 1250
Explanation-
Let the populations of villages A, B and C in 2015 are 3x, 2x and 5x respectively.
According to question,
34% of 3x + 39% of 2x + 20% of 5x = 700
1.02x + 0.78x + x = 700
2.8x = 700, x = 250
Population of village C in 2015 = 5 × 250 = 1250

Then,
42% of 5x + 23% of 6x = 1044
2.1x + 1.38x = 1044
3.48x = 1044, x = 300
Total population of these villages in these years together = 11 × 300 = 3300
Required number of people = 3300 – 1044 = 2256

Incorrect

Directions (Q6-10). Different number of employees work in six companies i.e. A, B, C, X, Y and Z. The number of employees in company B are 22% less than that of company A. The number of employees in company X are half the number of employees in company C. Number of employees in company Y is equal to the average number of employees working in company A and X. Number of employees working in company A are 140 more than the number of employees working in company X. Total number of employees working in companies B and C together are 1249.

Number of employees working in company Y are:

Correct

Answer- 4) 480
Explanation-
Let the number of employees working in company A are x.
Then,
Number of employees in company B = 78% of x = 0.78x
Let the number of employees in company X are y.
Then, number of employees in company C = 2y
Number of employees in company Y = (x + y)/2
According to question,
x – y = 140
Also,
0.78x + 2y = 1249
By solving both the equations, we have,
x = 550, y = 410

Number of employees in company A = 550
Number of employees in company B = 0.78 × 550 = 429
Number of employees in company X = 410
Number of employees in company C = 2 × 410 = 820
Number of employees in company Y = (550 + 410)/2 = 480

Incorrect

Answer- 4) 480

Number of employees in company B = 78% of x = 0.78x
Let the number of employees in company X are y.
Then, number of employees in company C = 2y
Number of employees in company Y = (x + y)/2
According to question,
x – y = 140
Also,
0.78x + 2y = 1249
By solving both the equations, we have,
x = 550, y = 410

Number of employees in company A = 550
Number of employees in company B = 0.78 × 550 = 429
Number of employees in company X = 410
Number of employees in company C = 2 × 410 = 820
