Question

if $19=80 marks, 16.1 Marks=100 francs, 25francs=£1 and £1/15=₹ 1, find the value of $3059 in rupees.
(ans:- ₹ 48000)​

Answer 1

Answer:

Yes, $3059 = Rs.48,000

Step-by-step explanation:

The principle is to express one unit of each currency in terms of one unit of the given currency.

We are given that:

$19 = 80 Marks; hence, $1 = (80/19) Marks

16.1 Marks = 100 Francs; hence, 1 Mark = (100/16.1) Francs

25 Francs = £1; hence, 1 Franc = (1/25)£

£1/15 = ₹1; hence £1 = ₹15

We need to express $ in terms of ₹. We need to find "x" so that $1 = ₹x

Now

$1/₹1 = ($1/1 Mark) * (1 Mark/1 Franc) * (1 Franc/£1) * (£1/₹1)

Using the conversions above, we get:

$1/₹1 = (4.2105)*(6.21118)*(0.04)*15

        = 15.6914

Hence $1 = ₹15.6914

=> $3059 = ₹(3059*15.6914)

                = ₹48000

$\frac{x}{y}$ = $\frac{x}{a}$ * $\frac{a}{b}$ * $\frac{b}{c}$ * $\frac{c}{y}$
