Answer 1

Answer:

1.SI=100P∗R∗T

       =1008000∗15∗5

        =Rs.6000

Amount=8000+6000=Rs.14000

Interest =Rs.6000 , Amount=Rs.14000

SI=100P∗R∗T

       =1006000∗12∗3

        =Rs.2160

Amount=6000+2160=Rs.8160

Interest =Rs.21600 , Amount=Rs.8160

Gain6000−2160

Gain =Rs.3840

2.Principal amount borrowed by Romesh  = Rs 2000

R =2% p a

T =2 years

Interest = 100P×R×T

= 1002000×2×2

= Rs 80

Principal amount borrowed by Romesh  = Rs 1000

R = 5 % p a

T = 2 years

Interest = 100P×R×T

= 1001000×5×2

= 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
