Step-by-step explanation:
Given Principal P = Rs 48,000
Time n = 2 years 3 months
= 2 + 312312 years
= 2 + 1414 years
= (8484 + 1414) years
= 9494 years
Amount A = Rs 55,660
A = p + 1
55660 = 48000 + I
I = 55660 – 48000
= Rs 7660
∴ Interest for 9494 years = Rs 7660
Simple interest = pnr100pnr100
7660 = 48000 x 9494 x r100r100
r = 7660×4×1009×480007660×4×1009×48000
= 7.09 %
= 7 %
Rate of interest = 7 % Per annum.

Answer:
Principal amount=48000 rupees
Rate=7.5%
Time=43years simple interest=(48000)(7.5)(43)/10
SI=154800rs
Total amount he should give=48000+154800=202800
He gives rupees 55000+ watch
.So watch should cost=202800-55000=147800rs
