$31\frac{3}{7}$ %
Let, total employees = 100
30% live over ten miles
30% employee = 30 employees
Live 10 mile or less 10 mile = (100 — 30)% = 70%
60% of 30 employee who live over 10 miles =$\frac{60×30}{100}$= 18 employees
The employees 40% use transport =$\frac{40×100}{100}$= 40 employees
The employees use transport who live 10 or less 10 miles = (40 — 18) = 22
Among 70 employees use transport = 22
Among 100 employees use transport =$\frac{22×100}{70}$ = $31\frac{3}{7}$ %
He used $\frac{9}{24}$ of his monthly salary for loan and rent
fit, the monthly salary be x;
Loan payment = $\frac{x}{6}$ and
Rent Payment =$\frac{x}{6}$ + 25% of $\frac{x}{6}$
= $\frac{5x}{24}$
um 0 can payment an rent payment = $\frac{x}{6}$ + $\frac{5x}{24}$
= $\frac{9x}{24}$
20
Here, Total +All singles-All both= 15 + 11 —6= 26—6=20
Since 6 is counted twice with cricket & football player number, so 6 has been deducted from the sum of cricket and football players’ number.
TK 10250
Total cost of 200 TV sets = 10,000 x 100 + 7500 x 100
= Tk. 17,50,000
Total selling price = Cost price + Profit
= 1750000 + 3,00,000 = Tk. 20,50,000
Selling price of each TV set =$\frac{2050000}{200}$= Tk. 10,250
1hour 48 minutes
Karim drove in 1.5 hours = 1.5 x 50 miles per hour = 75 miles
Total distance = 174 miles
Distance traveled at the rate of 55 miles per hour = 174 — 75 = 99 miles
$\text{Time=}\frac{\text{Distance}}{\text{speed}}$
= $\frac{99}{55}$ = $1\frac{4}{5}$
= 1 hour 48 minutes
