Answer:
amount invested in the account that earns 10% interest = Rs 3500
amount invested in the account that earns 8% interest =Rs 5500
Step-by-step explanation:
Two equations can be derived from the question
x + y = 9000 equation 1
0.08x + 0.1y = 790 equation 2
x = amount invested in the account that earns 8% interest
y = amount invested in the account that earns 10% interest
multiply equation 1 by 0.08
0.08x + 0.08y = 720 equation 3
subtract equation 3 from 2
0.02y = 70
divide both sides of the equation by 0.02
y = 70 / 0.02
y = 3500
Substitute for y in equation 1
x + 3500 = 9000
x = 9000 - 3500 = 5500
