it's b duhh bc imma geniud

Answer 2

B invested 3000 money for 6 months

Step-by-step explanation:

Let B's capital be x

B's capital for 6months = 6x

A's capital for 1 month = 1000

A's capital for 9 months = $9 * 1000 = 9000$

Total profit = 600

B received profit = 400

A received profit = $600 - 400 = 200$

Ratio of profit = Ratio of capital

$200 : 400 = 9000 : 6x$

$1 : 2 = 9000 : 6x$

$9000 / 6x = 1 / 2$

$9000 * 2 / 6x =1$

$9000 / 3 = x$

$3000 = x$

B's captial is 3000 for 6months.
