Answer 2

Answer:

Let's say the original rent was Rupees 100. He increased the rent by 15%.  So the value of increased rent will be 115 rupees.

Now he again decreased this rent by 10%.

10% of 115 rupees = 11.5 rupees.

115 - 11.5 = 103.5 rupees.

Therefore the percentage increase from original rent = 103.5 - 100/100 *100

= 3.5% increase
