Explanation

When two successive discounts are given, use the formula:

Overall Discount (%) = A + B - (A × B) / 100

Where:

A = first discount = 10%

B = second discount = 14%

So:

= 10 + 14 - (10 × 14) / 100

= 24 - 1.4

= 22.6%

Explanation

Multiply 50000 by 15 then divide by 100.

500 × 15 = 7500

Explanation

Let's assume the retail price is 100.

The distant price is 20% less than the retail price:

Distant price = 100 - (20% of 100)

= 100 - 20

= 80

James purchased the book at a 30% discount on the distant price:

Discount = 30% of 80

= 0.3 × 80

= 24

Price James paid = 80 - 24

= 56

As a percentage of the retail price:

(56/100) × 100 = 56%

Explanation

40% of 45 = (40 ÷ 100) × 45 = 18.

So, 18 is 40 percent of 45.

Explanation

Let the S.P = 100

then C.P. = 25

Profit = 75

Profit% = 75/25 * 100 = 300%

Explanation

To find the percentage of 0.001, follow these steps:

1. Multiply the number by 100 to convert it into a percentage:

   $$0.001\times 100=0.1$$

2. So, 0.001 as a percentage is 0.1%.

Explanation

To find the profit percentage:

Profit = Sale Price - Cost Price

= 750 - 570

= 180

Profit Percentage = (Profit / Cost Price) × 100

= (180 / 570) × 100

= 0.31579 × 100

≈ 31.578%

Explanation

(X/100) × (25/2) = 150

To get rid of the fraction, multiply both sides by 2:

(X/100) × 25 = 300

Now, divide both sides by 25:

X/100 = 300/25

X/100 = 12

Multiply both sides by 100 to solve for X:

X = 1200

Explanation

Principal (P) = 65000

Interest Rate (R) = 3% = 0.03

Interest Amount (I) = 68900 - 65000 = 3900 (since the interest amount is the total amount paid minus the principal)

We can use the formula: I = P × R × T

Rearranging the formula to solve for T, we get:

T = I / (P × R)

= 3900 / (65000 × 0.03)

= 3900 / 1950

= 2 years

So, it takes 2 years for the interest to become 68900.
