Question
A and B enter into a partnership with their initial sum
of Rs.28000 and Rs.40000 respectively. After 8 months, a third person C also joins them with his initial sum Rs.24000. After a year if total profit is Rs.5700 then find the profit share of B.Solution
Profit of A : B : C = 28000 x 12 : 40000 x 12 : 24000 x 4 = 7:10:2 Therefore, profit of B = (10/19) x 5700 = Rs.3000
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
