Write the extremes of the following:(a) 4 : 5 : : 16 : 20 (b) 1 : 6 : 4 : 24 (c) 25 : 30 : : 30 : 36
Given :
The given proportions are,
(a) 4 : 5 : : 16 : 20 (b) 1 : 6 : 4 : 24 (c) 25 : 30 : : 30 : 36
To do :
We have to write the extremes of the given proportions.
Solution :
In proportion a : b : : c : d,
'a' and 'd' are extremes.
'b' and 'c' are means.
(a) 4 : 5 : : 16 : 20
Therefore, in the given proportion 4 and 20 are extremes.
(b) 1 : 6 : 4 : 24
Therefore, in the given proportion 1 and 24 are extremes.
(c) 25 : 30 : : 30 : 36
Therefore, in the given proportion 25 and 36 are extremes.
