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
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
