If the revenue from online ticket sales in FY 2016-17 is denoted by *x*, by what percentage did the revenue from online ticket sales increase in FY 2016-17 compared to FY 2014-15, given that the revenues from online ticket sales in FY 2014-15 and FY 2015-16 were ₹ 600 crore and ₹ 900 crore respectively?

Question

Accepted Answer

**Solution:**

1. Let the revenue from online ticket sales in FY 2016-17 be *x* crore.

2. Given the average revenue for FY 2014-15, FY 2015-16, and FY 2016-17 is ₹ 1150 crore, we write the equation:
   
   $$\frac{600 + 900 + x}{3} = 1150$$

3. Multiply both sides by 3:
   
   $$600 + 900 + x = 3450$$

4. Simplify the left side:
   
   $$1500 + x = 3450$$

5. Solve for *x*:
   
   $$x = 3450 - 1500 = 1950$$

6. Calculate the percentage increase from FY 2014-15 to FY 2016-17:
   
   $$	ext{Percentage Increase} = \frac{1950 - 600}{600} 	imes 100 = \frac{1350}{600} 	imes 100 = 225\%$$

**Answer:** 225\%
