Question
In a school, Boys are 60% of total students. 50% Boys
students failed. Total 55% of students in school fail. employees in the company are working for more than 2 years. Find the percentage of Girls who pass?Solution
Let the total students in school = 100x Number of Boys = 60x Number of Girls = 40x Total failed students = 55x Total failed Boys = 50% of 60x = 30x Total failed Girls = 55x-30x= 25x Total number of Girls who are passed = 40x-25x = 15x 
Solve for x in the equation: 3(x + 2) + 2(2x - 5) = 5x + 9
If x = 19, then the value of x5 - 20x4 + 20x3 - 20x2 + 20x - 1 is
