A) 5430 B) 4430
C) 3430 D) 2430

(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.

 

x1+503x100+x1 +503x1002+x1 +503x1003 = 7620

 

 6x7+36x49+216x343=7620

 

 294x + 252x + 216x = 7620 x 343

 

 => x = 3430

 

 Amount of each installment = Rs.3430
