Question

If 1 euro is equal to $1.234 then what will be the value of  155 euros in terms of dollars ?

Answer 1

HINT- In order to solve this problem, we should use basic unitary methods along with some knowledge of currency ‘symbols of different countries just like dollar symbols used here.

Complete step by step answer:
In the question, it is given that,
$1euro = 1.234$; which means value of 1 euro equal to 1.2354 dollar
Mostly euro currency used in European countries like Italy, France and Germany etc.
We know that the unitary method is a technique for solving a problem by first finding the value of a single unit, then finding the necessary value by multiplying the single unit value. Overall this method is used to find the value of a unit from the value of a multiple, and hence the value of multiple.
So by using unitary method
$\because $ 1euro = $1.234$; Here value of single unit is given
$\therefore $155euros=1.234×155$=191.27$; which is the required value of multiple units.

Note- Whenever we face such types of problems the key concept we have to remember is that always use unitary method in which sometimes we might not have given value of single unit that we can also find from the value of a multiple, and hence the value of multiple from known single unit by multiplication with number of units.
