Speed $=45\; km/h=45\times \frac{\mathrm{5/}}{18}\text{m/s}=12.5\text{m/s}$
Time $=30\text{s}$

Distance traveled $=12.5\times 30=375$

Length of the bridge $=375-130=245\text{m}$

 

Square has four equal sides,

So distance covered twice = 8 km 

distance covered in pone side = 8/4 = 8/8 = 1 km

A Income = 40% 

B Income = 100% – 40%= 60%

B’s income more than A’s income = 60/40 * 100 

                                                            = 66.66%

 

 

 

C.P = 57,000       S.P= 60,000

Profit = S.P – C.P 

Profit = 60,000 – 57,000 = 3000

% Profit = ( 3000/57,000) * 100 = 5.23%

 

Profit = 25     C.P = 250

% Profit =(Profit/C.P) * 100 

% Profit = ( 25/250) * 100

% Profit = 10%
