Question 1:
From the question, we can conclude that;

Total earning = (Listed Share) x (Value/Share)

The first 9 months; (Jan - Sep)
Total earning = 5m x 7.2 = 36m (36 million dollars)

The 4th quarter; (Oct - Dec)
Total earning = 10m x 1.25 = 12.5m

Total Annual earning = 36m + 12.5m = 48.5m

At the end of the year, there are total 10m listed share; therefore,
the average annual per share = 48.5m / 10m = 4.85 dollar per share

(A)9/14 (B)3/4 (C)9/11
(D)6/7 (E)7/8

Assuming total rats = N
and total rats that died = D

Before experiment; male/female = 40N/60N

After experiment; Death Male/DeathFemale = 30D/70D

Death Rate amoung the male rat = 30D/40N

Deat Rate amount the female rat = 70D/60N

death rate among the male rats to the death rate among the female rats
= (30D/40N) / (70D/60N)

= 3 * 6 / 4*7 = 9/14
