A man deposits 5000 tk at 5% annual interest for six months. In every six
months he withdraws tk 500 from his principal plus interest earned. What is the

Total
Interest = 2.5%×5000 + 2.5%×4500 + 2.5%×4000 + 2.5%×3500 + 2.5%×3000 +
2.5%×2500 + 2.5%× 2000 + 2.5%×1500 + 2.5%×1000 + 2.5%×500

2x+1.5
y= 8000….(ii)
Now,
2×(i)-(ii)=>
We
get,
2x+2y=10000
2x+1.5y=8000
----------------------------------
0.5y=2000
=>
y=4000
and,
x+4000=5000
=>
x=1000
So,
Investment= 1000 and wages=4000 (Ans:)
