Step-by-step explanation:

Now while selling the shopkeeper cheats again for 10%, which results in 110 + 10% of 110 = 121. If he would have been honest he would have bought 100 units, but now he has 121 units. So he gains 121 - 100 = 21 units, which is 21 / 100 = 21% units. So, he gains a total of 21% units.
