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