Answers: 1.c 2.c 3.a 4.e 5.b


Perimeter of a square= 4*length of its one side

Ladies: 41.67% of 240= 100m (each side is 25m and area is 625m2)

Gents: 33.33% of 240= 80m (each side is 20m and area is 400m2)

Kids: 25% of 240= 60m (each side is 15m and area is 225m2)

From the above data we can arrive create the following table.
Bulb type
1 per 5 m2
1 per 25 m2
1 per each 4m of perimeter
data interpretation set 3

1. Ratio between the areas of ladies, kids and gents sections is 625:225:400= 25:9:16 (c)

2. Area of gents section- Area of kids section= 400-225=175m2

Furnishing charge is Rs.125/m2

Expense for furnishing extra 175m2= 175*125= 21875 (c)

3. Cost for lighting up the ladies section = 125*80+ 25*75+ 25*12= Rs.12175 (a)

4. Percentage of the LED bulbs utilised to light up the kids section= (45/250)*100= 18% (e)

5. Total number of LED, CFL, and incandescent bulbs in ladies and gents section together is 205, 41, and 45 respectively.

Therefore the total electricity consumption in a day= 205*0.2+ 41*0.4+ 45*1

= 102.4 (b)
