Explanation

To find 75% of 85000, you multiply 85000 by 0.75:

85000 * 0.75 = 63750

Explanation

To find 4.5% of 165,000, you multiply 165,000 by 4.5% (or 0.045):

165,000 * 0.045 = 7,425.

Explanation

To convert 4/ 5 into a percentage:

4/5 × 100% = 80%

To convert 4/5​ into a decimal:

4/5 = 0.8

So, the correct options are 80% and 0.8.

Explanation

1. Let the cost price of the first article be $C_1$ and the second article be C2​.

   
   

2. First article sold at 10% loss:

SP1​=C1​−0.1C1​=0.9C1​

Given SP1​=800,

0.9C1​=800⟹C1​=800/0.9​=888.89

3. Second article sold at 10% gain:

SP2​=C2​+0.1C2​=1.1C2​

Given: SP2​=800

1.1C2​=800⟹C2​=800/1.1​=727.27

4. Total cost price = C1​+C2​=888.89+727.27=1616.16

5. Total selling price =SP1​+SP2​=800+800=1600

6. Overall loss = Total CP – Total SP = 1616.16 – 1600 = 16.16

7. Overall loss percent = $frac{16.16}{1616.16} × 100 approx 1$

Answer:  1% Loss 

Explanation

A + B + C + D + E = 40 × 5 = 200

A + B = 35 × 2 = 70

C + D = 42 × 2 = 84

Therefore,

E = (A + B + C + D + E) - (A + B + C + D)

E = 200 - 70 - 84

E = 46 years

Explanation

Let's say B's income is 100%.

Then, A's income is 60% (since it's 40% less than B's).

To find out how much percent B's income is more than A's income, we need to find the difference between their incomes and divide it by A's income, then multiply by 100:

((B's income - A's income) / A's income) * 100

= ((100 - 60) / 60) * 100

= (40 / 60) * 100

= 66.66%

So, B's income is 66.66% more than A's income.

Explanation

Let the total number of boys be$x$.

45% of $x$ participated: $0.45\times x=135$.

Solve for $x$: $x=\frac{135}{0.45}$

$x=300$, so the total number of boys is 300.

Explanation

Original length = 72 cm, stretched length = 90 cm.

Increase in length = 90 − 72 = 18 cm.

Percentage increase = (Increase ÷ Original length) × 100.

Percentage increase = (18 ÷ 72) × 100 = 25%.

Therefore, the rope’s length increased by 25%.

Explanation

Explanation

Initial value = 12000

Depreciation = 5% per year

Year 1: 12000 × 0.95 = 11400

Year 2: 11400 × 0.95 = 10830

Year 3: 10830 × 0.95 = 10288.5

Year 4: 10288.5 × 0.95 = 9774.075 ≈ 9774
