Answer:
Normal selling price is Rs 4500
Explanation:
1) Selling price = original price × (100-d) / 100
d = reduced price percentage
2) Rearrange the formula
original price = (selling price × 100) / (100 - d)
S.p = 3825
d= 15%
let original price = x
Therefore
x = (s.p×100) / (100-d)
x = (3825×100) ÷ (100-15)
x = 382500/85
x = 4500
Answer:
Step-by-step explanation:
cot²(3x)=y
y²-3y+2=0
y²-y-2y+2=0
y(y-1)-2(y-1)=0
(y-1)(y-2)=0
y=1,y=2
cot3x=1
tan 3x=1=tan (π/4)=tan (nπ+π/4)
3x=nπ+π/4=(4nπ+π)/4=(4n+1)π/4
x=(4nπ+1)π/12,n is an integer.
cot 3x=2
tan 3x=1/2
3x=tan^{-1}(1/2)≈26.57°+360n
x≈8.86°+120n
