The geometric mean you would use is C
Answer: 72
heyy, umm basically group like terms together. E.g. 6= 1/2x + 1/4x - 2/3x. Then, just solve for x e.g. 1/2 + 1/4 - 2/3 and use the answer to equal it to 6. Which should be 1/12x=6... pretty sure haha. Then divide. E.g.6/1/12 for x. In this case I got 72.. :)
The sign would be negative
X is in the negative area meaning that when x/y and multiplied by y, it would stay negative since y is positive
Answer:
let cp be x
sp= 115x/100 ---(when 15%gain)
sp = 88x/100------(when 12% loss
according to question
115x/100 - 88x/100 = 81
or, (115x-88x)= 8100
or, 27x = 8100
or, x= 8100/27
x = 300
hence cp is RS 300
