A) 5430 | B) 4430 |

C) 3430 | D) 2430 |

Explanation:

Let each installment be Rs.x. Then,

(P.W. of Rs.x due 1 year hence) + (P.W of Rs.x due 2 years hence) + (P.W of Rs. X due 3 years hence) = 7620.

$\left[\frac{{\displaystyle x}}{{\displaystyle \left(1+\frac{50}{3x100}\right)}}\right]+\left[\frac{x}{1+{\left({\displaystyle \frac{50}{3x100}}\right)}^{2}}\right]+\left[\frac{{\displaystyle x}}{{\displaystyle 1+{\left(\frac{50}{3x100}\right)}^{3}}}\right]=7620$

$\frac{6x}{7}+\frac{36x}{49}+\frac{216x}{343}=7620$

$294x+252x+216x=7620x343$

=> x = 3430
