Question

Lata spent Rs.9.50 for buying a pen and Rs.2.50 for one pencil. How much money did he spend?

Answer 1

Hint: From the given details we get the amount spent on buying a pen to be 9.50 and the amount spent on buying a pencil to be 2.50. So the total cost is given by the sum of both the amounts.

Step by step solution :
We are given that Lata spent Rs.9.50 in buying a pen and Rs.2.50 for one pencil.
Hence,
Amount spent on buying a pen = 9.50
Amount spent on buying a pencil = 2.50
The total amount spent is given by adding both the amounts
Hence the total amount spent by Lata is
$\Rightarrow 9.50+2.50=12$

Therefore Lata spent Rs.12 for buying both a pen and pencil.

Note :
As we are asked for the total amount we add the amounts.
Same way if they ask for the difference or amount left the operation done will be subtracted.
