The price of the original shirt is $45, it is reduced to $32.50. Calculate the percentage decrease. Show your workings.
Answers
Answer:
The percent decrease in the price of shirt is 27.78%
Step-by-step explanation:
The percent decrease is the decrease in the price of a product or good.
Given
Original Price = $45
Decreased price = $32.50
Percentage decrease is calculated by using the formula
[tex]Percentage\ decrease = \frac{decrease}{Original\ price} *100\\[/tex]
And the decrease is calculated as:
[tex]Decrease = Original\ price - Reduced\ price[/tex]
So,
[tex]Decrease = 45-32.50 = 12.5[/tex]
Putting the values in the formula for percent decrease
[tex]Percent\ decrease = \frac{12.50}{45} *100\\=0.2777..*100\\= 27.77..[/tex]
Rounding off to nearest hundredth: 27.78%
Hence
The percent decrease in the price of shirt is 27.78%

the simple interest on a certain sum of money for 2(1/2) years at 12% per annum is Rs.40
Answers
Step-by-step explanation:
[tex] si = p \times \frac{r}{100} \times t[/tex]
[tex]si = 40 \times \frac{12}{100} \times \frac{5}{2}[/tex]
[tex]si = \frac{40 \times 12 \times 5}{100 \times 2} [/tex]
[tex]si = \frac{4 \times 12 \times 5}{10 \times 2} [/tex]
[tex]si = \frac{4 \times 12 }{5\times 2} [/tex]
[tex]si = \frac{2 \times 12}{5} [/tex]
[tex]si = \frac{24}{5} [/tex]
[tex]si = 4.8[/tex]
