The cost of 4 bags and 3 boxes is ₹555 and the cost of 3 bags and 4 boxes is ₹460. What is the cost of one bag ?
Answer & explanation
Correct answer: option 1
Let us consider that,
Cost of 1 bag = x and cost of 1 box = y
4x + 3Y = 555 ------(1)
and , 3x + 4y = 460 ------(2)
Multiply equation 1 by 4 and equation 2 by 3
16x + 12Y = 2220
and , 9x + 12y = 1380
After subtracting them,
7x = 840
x = 120
The correct answer is option (1) : ₹120
