### Solutions

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 Distribution Ladies Gents Kids Total LED 1 per 5 m2 125 80 45 250 CFL 1 per 25 m2 25 16 9 50 Incandescent 1 per each 4m of perimeter 25 20 15 60

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)

1. Ye itni tough di cat mein bhi nai ati h sir. Explanation and plz

1. Difficulty level is same as SBI PO

2. Sir......students ke jaan loge kya

2. Cat to job nhi deta hain but they will give us job

3. 4r1+4r2+4r3 = 240
4r1 = (33.33 * 240)/100 =>r1 = 20
similarly r2 = 25 and r3=15
now area is asked therefore r1^2/r2^2/r3^2 = 400/625/225
i have taken r1 r2 r3 in different pattern therefore pattern of answer is different but true answer is 25/9/16

1. You have to find ratios in the same order as given in the question. Here it is ladies:kids:gents.

4. 2nd part 20^2 - 15^2 = 175
therefore costing = 175*125 = 21875

5. what is the calculation of Bulb Table?? Can some plz explain?

6. ye solve krne me 10-12 min lagg jaege quesn samjh ke
