Answer:
44 minutes
Step-by-step explanation:
Money she pays for phone service: ₹145
Extra money she has to pay for 1 extra minute: ₹0.75
Bill of the last month: ₹178
Therefore, the extra money she had to pay: 178-145= ₹33
therefore, the number of minutes she had talked beyond the allowed time = 33/0.75 = 33 ÷ 75
100
= 33 x 100 = 11 x 100 = 11 x 4 = 44 minutes
75 25 1
