Pie

Answer:

A 20

Step-by-step explanation:

Given

Phone Battery Life (hours)

A 20

B 25

C 10

D 18

8.45% of the battery life of each mobile phone is used in a day by a typical user

Calculating Hours of battery life in a day for each mobile

A 20

Battery life for A = $\frac{8.45}{100}\times 20 = 1.69$ hours

B 25

Battery life for B = $\frac{8.45}{100}\times 25 = 2.11$ hours

C 10

Battery life for C = $\frac{8.45}{100}\times 10 = 0.845$ hours

D 18

Battery life for D = $\frac{8.45}{100}\times 18 = 1.52$ hours

Therefor Mobile phone A 20 uses a total of 1.69 hours of battery life in a day
