DIRECTIONS (Qs.95-97):
Given below is the information about
Solar plants installed in four different colonies W, X, Y, Z. Number of solar plants in colonies W, X, Y, Z are 24, 20, 15 and 12 respectively. Number of electricity units produced in one week by one solar plant when they operate with maximum efficiency in colonies W, X, Y, Z are 2 lakh units/week, 80000 units/ week, 1 Lakh units/week and 1.5 Lakh units/week respectively. Number of houses in each colonies W, X, Y, Z are 540, 240, 150 and 350 respectively. Total units produced are consumed equally by each house in the colony.
⇒ Different number of solar plants are operated in four different weeks
In first week number of solar plants are operative in colonies W, X, Y, Z are 75%, 50%, 40% and 75% respectively. In second week it is 50%, 75%, 60% and 50% respectively. In third week it is 75%, 100%, 80% and 50% respectively. In fourth week it is 100%, 50%, 60% and 75% respectively.
⇒ Given below is the three ranges of efficiency of a solar plants (number of unit produced /Week by one plant)

Three solar plants also operate on different levels
⇒ level 1 : Consider upper limit of range of efficiency
⇒ level 2 : Consider mid of range of efficiency
⇒ level 3 : Consider the lower range of efficiency
Eg. If a solar plants is operative at efficiency 2 then its level 2 efficiency will be =

45+55

2

= 50 %
Its level 1 efficiency will be 55%
Its level 3 efficiency will be 45%
