Explanation

Profit = Selling Price - Cost Price

= 390 - 300 = 90
Profit % = (Profit / Cost Price) × 100

= (90 / 300) × 100 = 30%

Explanation

Let the number of boys be x.

Number of girls is 120 – x.

Total number of chocolates received by boys and girls = 2x + 3(120 – x) = 300

=> 360 – x = 300 => x = 60.

So, the number of boys or girls is 60.

Original price = 4000

Discounted price = 2800

Explanation

Principal = 200,000

Rate = 5% per year

Time = 2 years

Simple Interest = (P × R × T)/100

= (200,000 × 5 × 2)/100

= 20,000

Total Amount = Principal + Interest

= 200,000 + 20,000

= 220,000

Explanation

Step 1: Set up the percentage formula

To find the percentage of students present, divide the number of present students by the total number of students and multiply by 100

Percentage = Present student/total student x 100

Step 2: Substitute values and simplify

Insert the given values into the formula and simplify the fraction:

= 1200/1500 x 100

= 12/ 15  x 100

Divide both the numerator and denominator by 3

= 4/5 x100

= 0.8 x 100

= 80%
