Question
Shivangi is suffering from anaemia as haemoglobin level in her blood is lower than the normal range. Doctor advised her to take one iron tablet two times a day. If the cost of 10 tablets is Rs. 17, then what amount will she be required to pay for her medical bill for 15 days?
Solution
Shivangi has to take iron tablets two times in a day.
Number of iron tablets she has to take in one day = 2.
Total iron tablets for 15 days = 15 × 2 = 30 tablets
∴ Cost of 10 tablets = Rs. 17
∴ Cost of 1 tablet = Rs. `17/10`
∴ Cost of 30 tablets = Rs. `17/10 xx 30` = Rs. 51
Hence, she has to pay Rs. 51 for her medical bill.
