Answer:
The fixed charge for two days was ₹ 4
&The charge for each extra day was ₹ 3
Step-by-step explanation:
Let the fixed charge for 2 days be ‘x’
Let the cost of book kept per day be ‘y’
Case 1:
x+4y=22[1]
Case 2:
x+2y=16[2]
On subtracting equations [1] & [2],
2y=6
∴y=3
∴x+2x6=16
∴x=4
∴The fixed charge for two days was ₹ 4
&The charge for each extra day was ₹ 3
Hope it helps!!!
