Solution

Shivangi has to take iron tablets two times in a day.
Number of iron tablets she has to take in one day = 2 [Given]

Total iron tablets for 15 days = 15×2=30 tablets

Using unitary method in which first we find the value of one unit and then the value of the required number of units.
Cost of 10 tablets = Rs. 17
Cost of 1 tablet = Rs. 1710
Cost of 30 tablets = Rs. 1710×30
= Rs. 51
Hence, she has to pay Rs. 51 for her medical bill.
