(E) None of these​

Answer 1

Answer:

Let winning time be a positive integer and losing time is a negative integer, as it is opposite of winning.

1 minute = 60 seconds

Therefore, Sana’s total difference time with Fatima

=10−60+20−25−37+12

=42−122

=−80 Seconds

Therefore, Sana lost the race by 80 seconds or by 1 min 20 seconds.

Which means Fatima, won the race.

Answer 2

Answer:

Answer: (D)

Explanation:

Isha' score: -10 + 90 - 25 + 15 - 60 + 8 - 20 = -2

Hence Angelina won the race by 2 seconds
