The table below shows the construction cost (in ? lakh) of Amabani's new bunglow

 Year 2013 2014 2015 2016 Inspection 25.5 10.5 5.5 2.5 Land 250 – – – Steel – 80 55 40 Bricks – 30 24 32 Other Building Material – 35 25 27 Labour 3.5 12.5 20 16 Painting – – – 35 Contigencies 1 7 6 2 Total 280 175 135.5 154.5

Important for :
1
The total construction cost is required to be kept within Rs 720 lakh by cutting the construction cost equally in all the years. This average reduction will be what percent of the total cost in the year 2015?
» Explain it
C
Total expenditure for all the years
=   280 + 175 + 135.5 + 154.5
=   Rs 745 lakh

If it has to be kept within Rs 720 lakh, then construction has to be reduced by Rs 25 lakh.

So, the construction cost reduced each year
 = 25 = Rs 6.25 lakh 4

Therefore, percentage reduction for 2015
 = 6.25 × 100 = 4.6% 135.5

Hence, optiion C is correct.

2
If few machines being used instead of labourers the labour cost gets reduced by 50%. Approximately, what percent of the total cost of 2016 is this reduced labour cost?

» Explain it
B
Total Labour cost
=   3.5 + 12.5 + 20 + 16
=   52

Cost of labour, getting reudced by 50% while using machines,
 = 52 = 26 2

According to the question,
 The reqd % = 26 × 100 154.5
= 16.8% = 17%

Hence, option B is correct.

3
Accroding to the market scenario the cost of steel rises by 10% each year from 2014 onwards, what is the ratio between the total of previous price and the total of new price?
» Explain it
B
Previous price of steel in all years together
=   80 + 55 + 40
=   Rs175 lakh

New price of the steel
=   110% of 80 + 110% of 55 + 110% of 40
=   88 + 60.5 + 44
=   Rs 192.5 lakh

Ratio = 175 : 192.5 = 10 : 11

Hence, option B is correct.

4
If the cost of bricks is reduced by 5% each year from 2014 onwards, then new cost price of bricks is approximately what percent of the inspection price of all the years?
» Explain it
D
The total bricks price of all years
=   30 + 24 + 32
=   Rs 86 lakh

After the reduction of 5%, the cost price
=   (100 – 5)% of 86 = 95% of 86
=   Rs 81.7 lakh

Inspection price of all years
=   25.5 + 10.5 + 5.5 + 2.5
=   44

According to the question,

 = 81.7 × 100 = 185.68 ≈ 186% 44

Hence, option D is correct.

5
The construction cost of a bunglow in 2013 is approximately what percent of the total construction cost of the bunglow from 2014 to 2016?
» Explain it
A
Constrcution cost of 2013 = Rs 280

Construction cost from 2014 to 2016
=   175 + 135.5 + 154.5
=   Rs 465 lakhs

 ∵  Reqd% = 280 × 100 465
=   60.21% ≈ 60%

Hence, option A is correct.
