\[1\] Euro \[ = 76.05\] rupees
\[1\] Rupees \[ = \$ 0.0152\]
Work out which jacket is the cheapest and by how many rupees.
The ______________jacket is cheapest by ________________rupees.

Answer 1

Hint: In this question, we have to convert the amount of jackets in rupees and compare which is the cheapest.
Here, the exchange rate is given, so we need to find the price in rupees then we will subtract the lower one from the greater one.

Complete step by step answer:
It is given that, on the internet, Pranay sees a grey jacket for \[165\] euros (euro) and a blue jacket for \[\$ 180\].
Also, the exchange rates are given,
\[1\] Euro = \[76.05\] rupees
\[1\] Rupee = \[\$ 0.0152\]
We need to find out the amount and compare which is the cheapest.
Pranay sees a grey jacket for \[165\] euros \[ = 165 \times 76.05 = {\text{Rs}}.{\text{ }}12,548.25\].
He sees a blue jacket for \[\$ 180\].
We can get the value in rupees by the unitary method.
We have, \[1\] rupee \[ = \$ 0.0152\]
\[ \Rightarrow \$ 1 = \dfrac{1}{{0.0152}}{\text{rupees}}\]
\[ \Rightarrow \$ 180 = \dfrac{{180}}{{0.0152}} = {\text{Rs}}.{\text{ }}11,842.10\]
Thus comparing the price of the grey jacket and blue jacket we get, the blue jacket is the cheapest.
Blue jacket is the cheapest by \[ = {\text{Rs}}.{\text{ }}\left( {12,548.25 - 11,842.10} \right) = {\text{Rs}}.{\text{ }}706.15\]

The Blue jacket is cheapest by \[{\text{Rs}}.{\text{ }}706.15\] rupees.

Note:
In this problem, we convert the value of the euro to rupee and value dollar to rupee. So we must give focus on conversions of values. We may go on that calculation. If there will be mistakes, the total problem will be wrong. Therefore we have to calculate the value correctly.
