What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We have:

In a foreign country, the coins are called parns(p), arns(a) and darns(d).

4 parns and 1 arn = 1 darn

2 arns 1 darn = 10 parns

4p + a = d

2a + d = 10p

2(4p + a = d)

8p + 2a = 2d

2a + d = 10p

8p - d = 2d - 10p

18p = 3d

d = 6p

Thus, 1 darns equals to 6 parns if Four parns and 1 arn equal 1 darn.Two arns and 1 darn equal 10 parns.
