Answer»

Answer:

50%

Step-by-step EXPLANATION:

From (i), (ii) & (iii) we get following relations,

M = (1 + MP/100)*C …… (1a)

S = (1 - 10/100)*M …… (1b)

S = (1 + 8/100)*(1 + 25/100)*C …… (1c)

From (1a), (1b) & (1c) we get,

(1 - 10/100)*(1 + MP/100)*C = (1 + 8/100)*(1 + 25/100)*C

or (1 + MP/100)*0.90 = 1.08*1.25

or 1 + MP/100 = 1.08*1.25/0.90 = 1.50

or MP/100 = 0.50 or MP = 50% …… (1d)

THEREFORE from (1d) it is evident that

the PERCENTAGE by how much the CLOTH should be marked up = 50%
