Solution

Interest for first year: 

S.I. = `("P" xx "r" xx "t")/100`

S.I. = `(12000 xx 15 xx 1)/100`

S.l. = 1800

Principal amount for second year = Rs ( 12,000 + 1800) = Rs 13,800 

Ramesh paid =Rs x (say) 

Therefore, new principal = Rs 13,800 - x 

A=Rs 9 200 ; r = 15 % ;  n = 1 year 

`"A" = "P" (1 + "r"/100)^"n"`

Rs 9,200 = Rs (13,800 - x)`(1 + 15/100)`

Rs 9 ,200 = Rs (13, 800- x) × 1.15

Rs 9,200 = Rs 15, 870 - Rs 1.15 x

1.15 x = Rs (15870 - 9,200) 

`"x" = "Rs"  6670/1.15`

x = Rs 5, 800 

Therefore, Amount Ramesh paid at the end of first year = Rs 5,800
