The table shows the battery life of four different mobile phones:

Mobile Phone Battery Life
Phone Battery Life (hours)
A 20
B 25
C 10
D 18


If 8.45% of the battery life of each mobile phone is used in a day by a typical user, which mobile phone would use a total of 1.69 hours of battery life in a day?

Answer 1

A is the answer.

Explanation:

I did the test.

Answer 2

A 20

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 =
`(8.45)/(100)* 20 = 1.69`hours

B 25

Battery life for B =
`(8.45)/(100)* 25 = 2.11`hours

C 10

Battery life for C =
`(8.45)/(100)* 10 = 0.845`hours

D 18

Battery life for D =
`(8.45)/(100)* 18 = 1.52`hours

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