Step-by-step explanation:

$\huge\tt\underline\red{QuestioN}:-$

If the cost of 93 m of a certain kind of plastic sheet is Rs 1395, then what would it cost

to buy 105 m of such plastic sheet?

TO FIND :-

The cost of 105m plastic sheet?

$\huge \tt\underline{\text{A} \blue{N} \orange{S} \pink{W} \green{E} \red{R}} :) :)$

Let the cost of the plastic sheet per meter be Rs.x

Length of plastic sheet ( in meter ) 93 105

Cost ( in Rs ) 1395 x

If more sheets are bought, the cost will also be more.

∴ It is a direct variation.

We get:93:105=1395:x

$= > \frac{93}{105} = \frac{1350}{x}$

Applying cross multiplication, we get:

$= > x = \frac{105 \times 1350}{93} \\ = > 1575$

∴ The required cost will be Rs.1,575.
