• Ans is (A) 926.10
  
  there is a equation to solve such kind of problem i read in a book which is
  when you have to pay an amount of X in N equal installment than amount of each installment will be?..
  let assume each installment amount is than,
  
  X= [ Y / ( 1+(r/100)) ] + [ Y / ( 1+(r/100))^2 ] + [ Y / ( 1+(r/100))^3 ] .......... upto N terms [ Y / ( 1+(r/100)) ^N ]
  
  here X=2522,
  
  2522= [y / ( 1+(5/100) )] + [y / ( 1+(5/100)^2 )] + [y / ( 1+(5/100)^3 )]
  
  y= 926.10

• x/(20/21) + x/(20/21)^2 + x/(20/21)^3 = 2522
  here x is the monthly installment.
  20/21= (1+r/100)
  x=926.10
