. A businessman invested a total of Rs. 9,000 in two savings accounts. One account earns 8% interest per year and the other earns 10% interest per year. At the end of the first year, the two investments earned a total of Rs. 790 in interest. Find how much he invested on each accounts.

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

i got 10.28 but that rounds up to 10.3

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
