  1. The price of 10% increased of an article of ₹ 100, then again 10% increased the price. How much is increased in total price.
    1. 20
    2. 21
    3. 110
    4. 121
Correct Option: B

10% of 100 = 10
New price = 110

Again, 10% of 110 = 110 x (10/100) = 11
New price = 110 + 11 = 121

∴ Required increment = 121 - 100 = 21
