Question

The cost of a school bag is ₹80 more than twice the cost of a tiffin box. Find the cost of school bag, if the total cost is ₹260

Answer 1

Cost of tiffin =x
Cost of school bag=2x+80
Total cost =260
=>260=x+2x+80
=>260=3x+80
=>260-80=3x
=>180=3x
=>x=180/3
=>x=60

Answer 2

Answer :-

$\huge{\underline{\boxed{\sf Rs. 200}}}$

$\bf\huge\underline{Solution:-}$

Let the cost of Tiffin box be - Rs. 'x'

therefore, the cost of school bag - Rs. '(2x + 80)'

Total cost of school bag and Tiffin - Rs. 260

According to question,

$\sf\rightarrow x + (2x + 80) = 260$

$\sf\rightarrow x + 2x + 80 = 260$

$\sf\rightarrow 3x + 80 = 260$

$\sf\rightarrow 3x = 260 - 80$

$\sf\rightarrow 3x = 180$

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

$\sf\therefore\bold x = 60$

Hence,

The cost of Tiffin box = Rs. 60

The cost of bag = Rs. (2 × 60 + 80)

= Rs. 200
