We have P= Rs 2000 at t=2% and n= 2
Then the interest = P*T*3
                         =  2000*2*2/100 = 80
Similarly interest on Rs1000 = 1000*5*2/100= 100
He has to pay back =2000 + 1000 + 80 + 100= 3180
ATQ  Cost of watch +2800= 3180
         Cost of watch = 3180 - 2800 = 380
Cost of the watch is Rs 380

Step-by-step explanation:

Principal amount borrowed by Romesh = Rs 2000

R =2% p a

T =2 years

Interest =

100

P×R×T

=

100

2000×2×2

= Rs 80

Principal amount borrowed by Romesh = Rs 1000

R = 5 % p a

T = 2 years

Interest =

100

P×R×t

=

100

1000×5×2

= Rs 100

Total amount that he will have to return = Rs. 2000 + 1000 + 80 + 100 = Rs. 3180

Amount repaid = Rs. 2800

Value of the watch = Rs. 3180 — 2800 = Rs. 380
