MBSB除權之前的最后交易價是2.55令吉
{(7 x 2.55) + (5 x 1.00)} + (5 x 1.00)} / 17 = 1.64

mum current price = 1.41
son current price = 0.705
current total investment value = {(12 x 1.41) + (5 x 0.705)} = 20.45
deducting additional cost to purchase right issue,
mom current price = {20.45 - (5 x 1.00)} / 7 = 2.21
in order for mum to retrace back to 1.80,

{TIV - (5 x 1.00)} /7 = 1.80
TIV = (1.80 x 7) + 5 = 17.60
{(12 x a) + (5 x 0.5a)} =17.60
a = 17.60/14.5 = 1.21
