The total amount invested is 2000 Rs.
Step-by-step explanation:
1st case:
r = 5% , r = 10%
x × 1 × 5/100 + y × 1 × 10/100=400
5x/100 + 10y/100 = 400
5x + 10y = 40000
x + 2y = 8000 ........(1)
2nd case:
x × 10/100 + y × 5/100 = 350
10x + 5y = 35000
2x + y=7000 .......(2)
Multiplying equation 1 by 2.
2x + 4y = 16000
2x + y. = 7000
By subtracting
3y = 9000
y = 9000/3 = 3000
Putting the value of y in equation 1
x = 8000 - 2y
= 8000-6000
= 2000 Rs
Thus the total amount invested is 2000 Rs.
