Answer: 14.29%
Step-by-step explanation:
Let C be the cost of 1 article and S the selling price for 1 article. The profit, P, for 1 article would be:
P = S - C
For n articles, the total profit would be
nP = nS - nC
Profit percentage would be (P/S)*100%
---------------------------------------------------------
We know that 21C = 18S: This can be written as C = (18/21)S
P = S - C
P = S - (18/21)S
P = (3/21)S or P=(1/7)S
Profit percentage would therefore be
(P/S)*100%
((1/7)S/S)*100%
(1/7)*100%
= 14.29%
Well there are 2 pecks in 1 kenning
So that's 2 × 1 peck = 1 kenning
2 kennings in 1 bushel
That's 2 × 1 kenning = 1 bushel
2 bushels in 1 strike
That's 2 × 1 bushel = 1 strike
4 strikes in 1 quarter
That's 4 × 1 strike = 1 quarter
4 quarters in 1 chaldron
That's 4 × 1 quarter = 1 chaldron
So now substitute again and again:
4 × 1 quarter = 1 chaldron
4 × ( 4 × 1 strikers ) = 1 chaldron
4 × ( 4 × ( 2 × 1 bushel ) ) = 1 chaldron
4 × ( 4 × ( 2 × ( 2 × 1 kenning ) ) ) = 1 chaldron
4 × ( 4 × ( 2 × ( 2 × ( 2 × 1 peck ) ) ) ) = 1 chaldron
4×4×2×2×2 peck = 1 chaldron
128 peck = 1 chaldron
So that's 128 × 1 peck = 1 chaldron.
Hope this helps.
