Question

javeen borrowed a sum of rupees 48000 at 7.5 % p.a for 3 years. calculate the amount and compound interest to be paid after 3 years ​

Answer 1

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 2

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
