Solution

The correct option is A

1,400


Solution:

The note Alex gave to the shopkeeper is that of ₹2000.
Let us count the various currency notes given by the shopkeeper back to Alex.
<Count the notes of different denominations>
There are 5 notes of ₹20 and one note of ₹500.
Amount of money given as ₹ 20 notes = 5 × 20 = ₹ 100
Amount of money given as ₹ 500 notes = 1 × 500 = ₹ 500
Total money given back by the shopkeeper = 500 + 100 = ₹ 600
Thus, the amount paid by Alex = ₹ 2000 - ₹ 600 = ₹ 1400
