Answer»

Answer:

  • Cost of a smartphone = Rs. 24500
  • Cost of a feature phone = Rs. 9750

Step-by-step explanation:

To Find:

  • The cost of a smartphone and a feature phone.

Let US assume:

  • The cost of a smartphone be x.
  • The cost of a feature phone be y.

The price of a smartphone is 5000 more than the cost of two feature phones.

  • i.e., x = 2Y + 5000 _____(i)

The cost of 4 feature phones and two smartphone is 88000.

  • i.e., 4y + 2x = 88000 _____(ii)

Finding the cost of a smartphone and a feature phone:

In EQUATION (ii).

⟿ 4y + 2x = 88000

Substituting the VALUE of x from eqⁿ(i).

⟿ 4y + 2(2y + 5000) = 88000

⟿ 4y + 4y + 10000 = 88000

⟿ 8y = 88000 - 10000

⟿ 8y = 78000

⟿ y = 78000/8

⟿ y = 9750

∴ Cost of a feature phone = Rs. 9750

In equation (i).

⟿ x = 2y + 5000

⟿ x = 2(9750) + 5000

⟿ x = 19500 + 5000

⟿ x = 24500

∴ Cost of a smartphone = Rs. 24500
