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
