A certain amount is distributed among A, B and C.A gets 3/10 and B gets ¼ of the whole amount. If C gets Tk. 81, then B gets:
সমাধান
সঠিক উত্তর: Option D
If whole amount is x
Then C gets = x - 3x/10 - x/4
= (40x - 12x -10x)/40
= 18x/40
Now, A/Q,
18x/40 = 81 tk
18x = 81*40 = 3240
x = 3240/18 = 180
Now,
B gets = x/4 = 180/4 = 45 tk
