4000 Was Divided Into Two Parts Such A Way That When First Part Was Invested At 3% And The Second At 5%, The Whole Annual Interest From Both The Investments Is?

Answer»

(X*3*1)/100 + [(4000 - x)*5*1]/100 = 144

3x/100 + 200 – 5x/100 = 144

2x/100 = 56 è x = 2800.

(x*3*1)/100 + [(4000 - x)*5*1]/100 = 144

3x/100 + 200 – 5x/100 = 144

2x/100 = 56 è x = 2800.
