Values:
Cost of each apple = Rs 20
No. of apples bought be Mrs. Cruz = 3 1/2
Amount she gave to the seller = Rs 1000
Solving:
1 dozen = 6 apples
3 1/2 dozens = (6 x 3) + 6/2
= 18 + 3
= 21 apples
Cost of one apple = Rs 20
So, cost of 21 apples = 21 x 20
= Rs 420
Therefore, the cost of the apples bought by Mrs. Cruz is Rs 420.
Amount she gave to the seller = Rs 1000
Amount she will receive as change = Rs 1000 - Rs 420
= Rs 580
Therefore Mrs. Cruz will receive Rs 580 back as change.
