ans: 49.6%.
Let, the marked price of the product be 100 Tk.
After allowing 36% commission, the retail price of the product will be = 100 – 36 = 64 Tk.
So, his selling price is 64 Tk.
At 8.8% profit, If selling price is Tk. 108.8 then cost price will be = Tk. 100
If selling price Tk. 64 then cost price will be = $\frac{100\times 64}{108.8}$ = 58.8235
After reducing commission by 24%
The actual commission will be = 36 – 24 = 12%
Then selling price = 100 – 12 = Tk. 88
Profit = 88 – 58.8235 = Tk. 29.1765
Profit percentage = $\frac{29.1765}{58.8235}$ x 100 = 49.6%
ans: A’s share 1600 Tk. B’s share 1800 Tk. & C’s share 1680 Tk.
A’s working capital for 12 months is Tk (4 X 5000 + 8 x 2500) = (20000 + 20000) = 40000 Tk
B’s working capital for 12 months is Tk (6 X 4500 + 6 X 3000) = (27000 + 18000) = 45000 Tk
C’s working capital for next 6 months is Tk (6 X 7000) = 42000 Tk
Capital ratio of A, B & C = 40000 : 45000 : 42000 = 40 : 45 : 42.
Sum of their capital ratio = 40 + 45 + 42 = 127.
A’s share = 5030 x $\frac{40}{127}$ = 1600 Tk.
B’s share = 5080 x $\frac{45}{127}$ = 1800 Tk.
C’s share = 5080 x $\frac{42}{127}$ = 1680 Tk.
12.5 days.
(2 men + 3 boys)’s 10 days work = (3 men + 2 boys)‘: 8 days works.
(20 men + 30 boys)’s 1 day work = (24 men + 16 boys)’s 1 day work.
=>4 men = 14 boys
=>1 men = $\frac{14}{4}$; boys
=>2 men =$\frac{14}{4}$x 2 boys = 7 boys.
=> 2 men + 3 boys = 7 boys + 3 boys = ID boys
and 2men+ l boy= 7 boys +1boy= 8 boys
l0 boys can do the work in = 10 days
8 boys can do the work in =$\frac{10×10}{8}$= 12.5 days.
