Answer : Option A

Explanation :

$MF#%\text{Rs.20000 after 4 years } = 20000\left(1 + \dfrac{10}{100}\right)^4 = 20000\left(\dfrac{11}{10}\right)^4 = \text{Rs. 29282}\\\\ \text{Rs.20000 after 3 years} = 20000\left(1 + \dfrac{10}{100}\right)^3 = 20000\left(\dfrac{11}{10}\right)^3 = \text{Rs. 26620}\\\\ \text{Rs.20000 after 2 years } = 20000\left(1 + \dfrac{10}{100}\right)^2 = 20000\left(\dfrac{11}{10}\right)^2 = \text{Rs. 24200}\\\\ \text{Rs.20000 after 1 year } = 20000\left(1 + \dfrac{10}{100}\right)^1 = 20000\left(\dfrac{11}{10}\right) = \text{Rs. 22000}$MF#%
Total amount after 4 years = 29282 + 26620 + 24200 + 22000 = Rs. 102102
