To calculate the percentage of profit,

*The cost price of the refrigerator = 11,500 rupees. *The man spent an additional rupees to fix the refrigerator is = 1500. Therefore, the total cost spent by the man is =

11,500 + 1,500 = 13,000 rupees.

The selling price of the refrigerator is 15,500 rupees.

To calculate the profit, we subtract the cost price from the selling price:

Profit = Selling price – Cost price

Profit = 15,500 – 13,000 = 2,500 rupees.

Now, we can calculate the percentage of profit by dividing the profit by the cost price and multiplying by 100:

Percentage of Profit = (Profit / Cost price) * 100

Percentage of Profit = (2,500 / 13,000) * 100 ≈ 19.23%

Therefore, the man made approximately a 19.23% profit through this transaction.

Here’s the answer:

1. To find the number of students who like to study English, we need to multiply the total number of students by the fraction 1/6:

Number of students who like to study English = (1/6) * 48 = 8 students.

2. To find the number of students who like to study Malayalam, we need to multiply the total number of students by the fraction 3/6:

Number of students who like to study Malayalam = (3/6) * 48 = 24 students.

3. To find the number of students who like to study Hindi, we need to subtract the sum of students who like English and Malayalam from the total number of students:

Number of students who like to study Hindi = 48 – (8 + 24) = 48 – 32 = 16 students.

Therefore, the answers to the questions are:

1. There are 8 students who like to study English.

2. There are 24 students who like to study Malayalam.

3. There are 16 students who like to study Hindi.

According to the given question, we have:

x + y = 34

They have given one of the number is 18, so by substituting it we get the following equation.

x + 18 = 34

To find the value of ‘x’, we’ll solve this equation:

x = 34 – 18

x = 16

Therefore, the other number is 16.
