A shop sells floor tiles at Rs 48 per square meter. A building contractor employees
machine that polishes
the tiles that damages 10% of the total number of
tiles which cannot be used
any
more. Calculate the
amount that need to be paid by contractor to tile
Shop owner, if the hall is of a square shape and
has a perimeter of 400m
a. Rs 400.000
b. Rs 600 000
c. 528000 d.365000

c. 528000

Step-by-step explanation:

The computation of the amount that need to be paid is shown below:

Let us assume the side of the square shaped hall be X meter s

So,

Perimeter = 4X

Now

4X = 400

X = 100m

Now

Area of the hall = 100 × 100 = 10000 sq. meter.

And,

The cost on total tiles is

= 10,000 × 48 = Rs. 480000

But, there is 10% damage has occurred that involved in the cost

So,

Total cost is

= Rs 480,000 + 10% of 480,000

= 480,000 + 48,000

= Rs. 5,28,000

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
