Question
A vendor priced an item 45% higher than its cost price. If
he sells it at a 5% discount, what is the vendor's gain percentage?Solution
ATQ,
Let the cost price of the item be Rs. '150b'
So, marked price = 150b * 1.45 = Rs. '217.5b'
So, selling price = 217.5b * 0.95 = Rs. '206.625b'
So, required gain percentage = {(206.625b - 150b)/150b} * 100 = 37.75%
I. 15/(√x)+9/(√x)=11√x
II. (√y)/4 + (5√y)/12 = 1/(√y)
I. 84x² - 167x - 55 = 0
II. 247y² + 210y + 27 = 0
I. x3 = 1728
II. y2 – 15y + 56 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 11x² - 93x + 88 = 0
Equation 2: 13y² + 118y + 93 = 0
I. 2x2 - 9 x + 9 = 0
II. 2y2 - 7 y + 3 = 0
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between x and y.
I. x
Find the remainder when x⁵ − 3x⁴ + 4x³ − 6x² + 8x − 3 is divided by (x − 2).
If x + 1/x = 4, find x⁵ + 1/x⁵.
I.√(3x-17)+ x=15
II. y+ 135/y=24
Between what values of x is the expression 19x - 2x2 - 35 positive?
