Question
A trader marked an article 35% above its cost price and
sold it after allowing a discount of 20%. If the transaction resulted in a profit of Rs. 34, then find the cost price of the articleSolution
Let the cost price of the article be Rs. βxβ Marked price of the article = x Γ 1.35 = Rs. β1.35xβ Selling price of the article = 1.35x Γ 0.8 = Rs. β1.08xβ Profit = 1.08x β x = Rs. β0.08xβ ATQ; 0.08x = 34 So, x = 425 Therefore, cost price of the article is Rs. 425.
If (x β1.3)3+(xβ1.4)3+(xβ1.5)3 = 3(xβ1.3)(xβ1.4)(xβ1.5), Then x = ?
If (x + y + z) = 68, (x/z) = (3/4) and (z/y) = (2/5), then find the value of βyβ.
What is the simplified form of the expression?
(1 + x) (1 + xΒ²) (1 + xβ΄) (1 + xβΈ) (1 β x)?
A.(1-x40)
B.(1-x1...
