Answer 2

Answer:

x=1,y=2,z=-3 ...(d)

Explanation:

Principle (P)=Rs.5000

Rate (R)=8%p.a

Time (T)=23 December 2011 to 29 july 2012

Dec. Jan. Feb. March April May June July

8 31 29 31 30 31 30 29

Total 219 days =

365

219

years

=∴ Interest =

100

PRT

=

100×365

5000×8×219

=10×8×3=240

∴ Amount =P+I=Rs.5000+240=Rs.5240
