Raju bought an old car for Rs.125000 and spent Rs.25000 on its repair . He sold the car for Rs.200000 . Find his gain or loss pe

Keith_Richards [23]

Answer: $33.33\%$

Step-by-step explanation:

Given

Raju buy an old car for $Rs\ 1,25,000$

He spent $Rs\ 25000$ on its repair

The selling price of the car $Rs\ 2,00,000$

So, the cost price is

$\Rightarrow C.P.=1,25,000+25,000=Rs\ 1,50,000$

Here, $S.P.> C.P.\quad \text{i.e. gain}$

Gain percent is

$\Rightarrow \text{Gain percent}=\dfrac{2,00,000-1,50,000}{1,50,000}\times 100=\dfrac{50,000}{1,50,000}\times 100\\\Rightarrow \text{Gain percent}=33.33\ \%$

The function f(x)=58(1.6)x represents the possible bird population in a park x years from now. Each year, the expected number of

-BARSIC- [3]

Answer:

1.6 times or 60% more than

Step-by-step explanation:

The question seems to be asking about the growth factor in the given exponential function.

<h3>Exponential function</h3>

A generic exponential function will have the form ...

quantity = (initial value) × (growth factor)^(number of intervals)

Comparing this form to the given formula ...

f(x) = 58 × 1.6^x

we see the "growth factor" is 1.6. This is the multiplier from one interval (year) to the next.

Each year the expected number of birds is 1.6 times the number the year before.

Additional comment

A growth factor is sometimes expressed in terms of a growth rate, usually a percentage.

growth factor = 1 + growth rate

1.6 = 1 + 0.60 = 1 + 60%

The growth rate of this bird population is 60% per year. Each year, the population is 60% more than the year before.

A rectangle has sides of 4x cm and x cm. the sides of the rectangle are all increased by the same length.if the perimeter of the

Verdich [7]

Answer:

4 cm

Step-by-step explanation:

The perimeter of the original rectangle is ...

P = 2(L+W) = 2(4x + x) = 10x

The perimeter of the larger rectangle after we add "a" to each side is ...

P = 2(L +W)

= 2((4x+a) +(x+a))

= 10x +4a = 10x +16

4a = 16 . . . . . subtract 10x from both sides

a = 4 . . . . . . . divide by 4

The length added to each side is 4 cm.
