Answer 1

Hii Dear,

◆ Answer -

Amount invested at 3% rate = 2500 Rs

Amount invested at 2% rate = 3500 Rs

◆ Explaination -

Let x be the amount invested at 3 %. Then sum invested at 2 % rate is 6000-x.

Interest obtained at 3 % rate -

Interest = x × 3/100

Interest obtained at 2 % rate -

Interest = (6000-x) × 2/100

Total interest obtained is given as -

Total interest = x × 3/100 + (6000-x) × 2/100

145 = 3x/100 + 120 - 2x/100

25 = x/100

x = 25 × 100

x = 2500 Rs

Amount invested at 3% rate = 2500 Rs

Amount invested at 2% rate = 6000-x = 3500 Rs

Thanks dear...
