Examples Where You Can Use Math In Daily Life

Below we have created some daily life problems where you can use Math to solve them.

Certainly, here are the same real-life problems from India with specific calculations involved:

Maths In Train Travel

Problem: Priya is planning a train journey from Chennai to Mumbai, and she wants to calculate the total fare for her family of four. The individual ticket price is ₹1,200, and there is a 5% GST on the fare.

Solution: Priya calculates the total fare as follows:

  • Ticket price per person = ₹1,200
  • Number of passengers = 4
  • Total ticket cost = ₹1,200 x 4 = ₹4,800
  • GST (5%) = 0.05 x ₹4,800 = ₹240
  • Total fare = ₹4,800 + ₹240 = ₹5,040

Maths In Agricultural Yield

Problem: A farmer in Punjab wants to estimate the expected yield of wheat from his field. His field area is 5 acres, and the expected yield is 3,000 kg per acre.

Solution: The farmer calculates the expected yield as follows:

  • Field area = 5 acres
  • Expected yield per acre = 3,000 kg
  • Total expected yield = 5 acres x 3,000 kg/acre = 15,000 kg

Math In Gold Jewelry Purchase

Problem: Raj wants to buy gold jewelry. The weight of the gold is 20 grams, and the making charges are ₹1,000 per gram. The GST rate is 3%.

Solution: Raj calculates the total cost as follows:

  • Gold weight = 20 grams
  • Making charges per gram = ₹1,000
  • Cost of gold (20 grams x ₹1,000/gram) = ₹20,000
  • GST (3%) = 0.03 x ₹20,000 = ₹600
  • Total cost = ₹20,000 + ₹600 = ₹20,600

Math In Electricity Bill

Problem: Mr. Sharma wants to calculate his monthly electricity bill. He consumed 300 units, and the electricity rate is ₹6 per unit.

Solution: Mr. Sharma calculates the bill as follows:

  • Units consumed = 300
  • Rate per unit = ₹6
  • Total bill = 300 units x ₹6/unit = ₹1,800

Maths In Vehicle Fuel Efficiency

Problem: Rahul wants to determine the fuel efficiency of his car. He traveled 300 kilometers and used 20 liters of fuel.

Solution: Rahul calculates his car’s fuel efficiency as follows:

  • Distance traveled = 300 kilometers
  • Fuel used = 20 liters
  • Fuel efficiency (km/l) = 300 km / 20 liters = 15 km/l

Maths In Tax Calculation

Problem: Preeti needs to calculate her income tax liability for the financial year. Her annual income is ₹6,00,000, and she has deductions of ₹1,50,000.

Solution: Preeti calculates her tax liability as follows:

  • Annual income = ₹6,00,000
  • Deductions = ₹1,50,000

Math In Loan EMI

Problem: Suresh is planning to take a personal loan of ₹50,000 with an interest rate of 12% for 3 years.

Solution: Suresh calculates the equated monthly installment (EMI) as follows:

  • Loan amount = ₹50,000
  • Annual interest rate = 12% = 0.12
  • Loan tenure = 3 years = 36 months
  • EMI = (Loan amount x Monthly interest rate) / [(1 – (1 + Monthly interest rate)^(-Loan tenure))]
  • EMI = (₹50,000 x 0.01) / [(1 – (1 + 0.01)^(-36))]

Math In Currency Exchange

Problem: Ramesh is traveling abroad and wants to exchange ₹10,000 into US Dollars at an exchange rate of ₹75 per USD.

Solution: Ramesh calculates the amount of foreign currency he will receive as follows:
