Question

please give me the answer of question 10

Answer 1

Let the cost of tiffin box be x

Given, cost of school bag is twice more than the cost of tiffin box = 2x

Given,cost of school bag is rs 80 more than twice the cost of tiffin box = 2x + 80

Givenz total cost = rs 260


A/q,

x + 2x + 80 = 260

3x + 80 = 260

3x = 260 - 80

3x = 180

x = $\dfrac{180}{3}$

x = 60



$\therefore{}$ The cost of tiffin box => x => rs 60


$\therefore{}$ Cost of school bag => 2x + 80 => 2 × 60 + 80 => rs 200

Answer 2

Let the cost of tiffin box = x

Then the cost of school bag is rs 80 more than twice the cost of tiffin box = 2x + 80

Total cost = Rs. 260


Now according to the Question:

x + 2x + 80 = 260

3x + 80 = 260

3x = 260 - 80

3x = 180

x = 180/3

x = 60



The cost of tiffin box = x =Rs 60


Cost of school bag =2x + 80
=2 × 60 + 80
=rs 200
