Given below is the information about wind mills in four different villages A, B and C and D. Number of wind mills in villages A, B, C and D are 24, 20, 15 and 12 respectively. Number of electricity units produced in one week by one wind mill when they operate with maximum efficiency in village A, B, C and D is 2 lakh units/week, 80000 units/ week, 1 Lakh units/week and 1.5 Lakh units/week respectively. Number of houses in each village A, B, C and D are 540, 240, 150 and 350 respectively. Total units produced are consumed equally by each house in the village

Total units produced in village C in the second and fourth week at level 1 efficiency of range 1 is what percent of the total units produced in village A in the first and fourth week at level 2 efficiency of range 1?

Accepted Answer

**Solution:**

1. Calculate the number of mills operating in village C during the second and fourth weeks:
   - Second week: $\frac{3}{5} 	imes 15 = 9$ mills
   - Fourth week: $\frac{3}{5} 	imes 15 = 9$ mills

2. Total mills operating in village C for these two weeks combined:
   $$9 + 9 = 18$$

3. Units produced per mill at level 1 efficiency of range 1 is the upper limit, which is 70%.

4. Units produced by village C mills:
   $$18 	imes 100,000 	imes \frac{70}{100} = 18 	imes 100,000 	imes 0.7 = 1,260,000 	ext{ units}$$

5. Calculate the number of mills operating in village A during the first and fourth weeks:
   - First week: $24 	imes \frac{3}{4} = 18$ mills
   - Fourth week: $24$ mills

6. Total mills operating in village A for these two weeks combined:
   $$18 + 24 = 42$$

7. Units produced per mill at level 2 efficiency of range 1 is the midpoint of 60% and 70%, which is 65%.

8. Units produced by village A mills:
   $$42 	imes 200,000 	imes \frac{65}{100} = 42 	imes 200,000 	imes 0.65 = 5,460,000 	ext{ units}$$

9. Required percentage:
   $$\frac{1,260,000}{5,460,000} 	imes 100 = \frac{126}{546} 	imes 100 = 23 \frac{21}{273} \%$$

**Answer:** 23 \frac{21}{273} \%
