Question

Please answer all the three questions correctly.​

Answer 1

Answer:

Area of Floor = 1.89

Are of each tile = 0.09

Number of tiles required = Area of Floor/ Area of each tile

$\frac{1.89}{0.0 } = 21$

hence 21 Tiles are required

Cost of 1 tile = 12.50 Rs

Cost of 21 Tiles =

$21 \times 12.5 = 262.5$

Hence The tiles will cost 262.5 Rs

CHANGE TO BE GIVEN TO FATHER = 737.5 Rs

Answer 2

Answer :

------------------------------------------

(a)

Here,

1 tile covered 0.09 m² area

So, How many tiles covered whole area (1.89 cm²) of floor

$\sf = \frac{1.89 × 1}{0.09}$

$\sf \underline{\fbox{= 21 tiles} }$

------------------------------------------

(b)

If cost of 1 tile is ₹12.50

Then cost of 21 tiles is

$\sf = 12.50 × 21$

$\sf \underline {\fbox{= 262.5}}$

------------------------------------------

(c)

If Gopal 's father gave him ₹ 1000

Then how much he will return to father ?

$\sf = ₹1000 - ₹262.5$

$\sf \underline{\fbox{= ₹737.5}}$
