Answer 2

Answer:

Cost Price of Calculator = RS.400

Step-by-step explanation:

So, it is mentioned that the shopkeeper gains 10%

Then it means; 440 = 100% + 10% ( cost price = 100%)

"440 = 110%"

And here we can use the unitary method:-

440= 110%

1% = Rs. 4

100% = 400

Hence; Cost price = Rs. 400
