**What is Unitary Method?**

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let’s say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let’s say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The exchange rate was 7.15 rand to $1.

So, the exchange rate of $1000 in Rands

= 1000×7.15

=7,150 rands.

B) Sophia spent 6,274.

Money left = 7,150-6274

= 876.

Now, exchange rate 1 rand= $0.14

In exchange rate

= 876×0.14

= $122.64
