Question

Shivangi is suffering from anaemia as haemoglobin level in her blood is lower than the normal range. A doctor advised her to take one iron tablet two times in 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?

Answer 1

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

$\therefore$ Total iron tablets for 15 days = $15\times 2=30$ tablets

Using unitary method in which first we find the value of one unit and then the value of the required number of units.
$\because$ Cost of 10 tablets = Rs. 17
$\therefore$ Cost of 1 tablet = Rs. $\frac{17}{10}$
$\therefore$ Cost of 30 tablets = Rs. $\frac{17}{10}\times 30$
= Rs. $51$
Hence, she has to pay Rs. 51 for her medical bill.
