Khi o lng cua to trng la: x * tong quy lng cua to= x * (Quy lng chnh + Quy lng tang ca + Quy lng chu nhat).

Theo yeu cau cua TG, viec ha n gia phai am b3o quy lng khong

oi, tc la: quy lng mi cua to + lng cua to trng = quy lngcu, ta co phng trnh sau:

( [(29 100 000 * k / ( NCC + NCTC + NCCN)] * NCC + [(29 100 000 * k / ( NCC +NCTC + NCCN)] * NCTC * 1.5 + [(29 100 000 * k / ( NCC + NCTC + NCCN)] *NCCN * 2 ) + x * ( [(29 100 000 * k / ( NCC + NCTC + NCCN)] * NCC + [(29100 000 * k / ( NCC + NCTC + NCCN)] * NCTC * 1.5 + [(29 100 000 * k / ( NCC +NCTC + NCCN)] * NCCN * 2 ) = 29 100 000

Rut gon phng trnh tren ta co:

k* [ (NCC + NCTC * 1.5 + NCCN * 2) / (NCC + NCTC + NCCN)] ( 1+ x) = 1

vay k = (NCC + NCTC + NCCN) / (NCC + NCTC * 1.5 + NCCN * 2) / (1 + x)
