SOLUTION
Let the money invested in scheme A = Rs.x
& money invested in scheme B= Rs. y
Now, schemes A & B offer interest at the rate of 8% per annum & 9% per annum respectively & she received and annual interest of Rs. 1860
This means 8% of x +9% of y= 1860
=) .08x+ .09= 1860.......…...(1)
Now if she interchanges the amount invested in each scheme, she will get Rs. 20 more as an annual Interest.
This means 8% of y +9% of x = 1860+20
=) .08y+ .09x= 1880...........(2)
Now we solve (1) &(2) for x & y
& we get x= 12000 , y= 10000
So, money invested in scheme A = Rs.12000
& money invested in Scheme B= Rs.10000.
