The price of a pen is Rs.42 and of the note-book is Rs.18. Calculate how many pens and note-books you can buy for Rs.480 in equal quantity?

  • (A) 8,8
  • (B) 7,7
  • (C) 9,9
  • (D) 6,6
  • Solution: We need to buy the pens and notebooks in equal numbers, with the total cost amounting to Rs. 480.
  • Each pen costs Rs. 42.
  • Each notebook costs Rs. 18.
  • Let the number of pens be represented by the variable x. Similarly, let the number of notebooks also be represented by the variable x.
  • Therefore, the total cost can be written as follows:
  • 42x + 18x = 480.
  • 60x = 480.
  • x = 480 / 60.
  • x = 8.
  • You can buy 8 pens and 8 notebooks.
