Step-by-step explanation:
Correct option is
A
380
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
