Example 12 We also saw this earlier in the case of Irfan purchasing a biscuit packet (₹15) and a toor dal packet (₹56). When he paid ₹100, the change he gets in rupees is: Price for biscuits = Rs 15 Price for toor dal = Rs 56 Total amount he had = Rs 100 Now, Amount he got back = Total Amount – (Price of toor dal + Price of biscuit) = 100 – (56 + 15) = 100 – 71 = 29 So, change he got back is Rs 29
