Question

Neetu in Hospital
Neetu has to take 3 injections in a day for 5 days.

How much medicine will she need for one day?

How much medicine in all for 5 days?

Answer 1

Quantity of medicine in 1 injection = 5 mL
It is given that Neetu has to take 3 injections in 1 day for 5 days.
So, quantity of medicine in 3 injections = 3 × 5 mL
= 15 mL
Thus, Neetu will need 15 mL of medicine in 1 day.
Quantity of medicine needed by Neetu in 1 day = 15 mL
Quantity of medicine needed by Neetu in 5 days = 5 × 15 mL
= 75 mL


Working: $\begin{array}{ccc}& 1& 5\\ & \times & 5\\ & 7& 5\\ & & \end{array}$
Thus, Neetu will need 75 mL of medicine in 5 days.
