The activity of cash can be represented by the cash flow diagram below. The idea of the solution is to equate all the payments to all the debts in a common time. What we did below is we equate all cash activities in Jan. 1, 1983.

$F = P(1 + i)^n$

$F_1 = 9,000(1 + 0.12)^5 = \text{P}15,861.08$

$F_2 = 12,000(1 + 0.12)^3 = \text{P}16,859.14$

$F_3 = 7,000(1 + 0.12)^2 = \text{P}8,780.80$

$F_4 = X(1 + 0.12) = 1.12X$
 

$1.5X + F_3 + F_4 = F_1 + F_2$

$1.5X + 8,780.80 + 1.12X = 15,861.08 + 16,859.14$

$2.62X = 23,939.42$

$X = \text{P}9,137.18$

$1.5X = \text{P}13,705.77$
