Question

4. A playground is in the shape of a rectangle.
A sum of Rs. 1000 was spent to make the
ground usable at the rate of 25 paise per
m². The breadth of the ground is 50 m. If
the length of the ground is increased by
20m, what will be the expenditure, in Rs.)
at the same rate per m²?​

Answer 1

Answer:

Rs 1250

Step-by-step explanation:

Let the length =x m

then area=50*x m²

Expenses for making the ground usable

=25*50x/100 Rs

=1250x/100=12.5x=1000

x=1000/12.5=80 m

if length is increased by 20 m

Then length=100 m

Thus new expenses=(100/80)*1000

=100000/80=10000/8

=Rs 1250
