Multiply by 2-digit numbers: word problems

  • Multiplication with 2-digit numbers means using numbers from 10 to 99 as multipliers.
    Example: 23×1223 \times 1223×12.
  • Word problems require reading carefully, understanding the situation, and then applying multiplication.
  • Steps to solve:
  • Step 1: Read the problem carefully.
  • Step 2: Identify the numbers and what is being asked.
  • Step 3: Choose the operation (here: multiplication).
  • Step 4: Solve using the multiplication method (long multiplication, box method, or lattice).
  • Step 5: Write the final answer in a sentence.

Example 1:
A bus has 48 seats. If 23 buses are used for a school trip, how many students can travel in total?

👉 Solution: 48×23=1,10448 \times 23 = 1,10448×23=1,104

Answer: 1,104 students can travel.


Example 2:
A farmer has 36 mango trees. Each tree produces 25 mangoes. How many mangoes are there in total?

👉 Solution: 36×25=90036 \times 25 = 90036×25=900

Answer: The farmer has 900 mangoes.


Example 3:
A book has 72 pages. If a school buys 14 such books, how many pages are there in all?

👉 Solution: 72×14=1,00872 \times 14 = 1,00872×14=1,008

Answer: There are 1,008 pages in all.


  • Look for keywords like each, every, total, altogether → these usually mean multiplication.
  • Double-check the numbers before solving.
  • Always write the answer in a complete sentence.

  • A pen costs ₹35. How much will 28 pens cost?
  • A school has 46 classrooms. Each classroom has 32 chairs. How many chairs are there in total?
  • A factory produces 58 bottles each day. How many bottles will it produce in 24 days?
