Answer:
5 parns
Step-by-step explanation:
4 parns and a arn equal 1 darn and 4 + 1 is 5
1 darns equal to 6 parns if Four parns and 1 arn equal 1 darn.Two arns and 1 darn equal 10 parns.
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.
