The income of a company increase 20% per annum. If its income ₹26,64,000 in the year 2012, then its income in the year 2010 was:

Solution

Let income in year 2010 = Rs. $$x$$

Increase % every year = 20%

Thus, income in 2012 = $$x(1+\frac{20}{100})^2=26,64,000$$

=> $$x(\frac{6}{5})^2=26,64,000$$

=> $$x=26,64,000\times\frac{25}{36}$$

=> $$x=74,000\times25=18,50,000$$

$$\therefore$$ Income in 2010 was Rs. 18,50,000

=> Ans - (C)
