1. In three rounds of a quiz Reena secured - 10,5
and 25. Find her final score.
​

Answer 1

Answer:

1. 23 + 56 = 79
2. -23 + 50 = 27
3. -97 + (-24) = -121
4. -14 + (-20) = -34
5. 40 + (-20) = 20
6. -17 + 25 = 8
7. 0 + 5 = 5
8. 17 + (-17) = 0

reena scored in first round = -10

reena scored in second round = 5

reena scored in third round = 25

total score = (-10) + 5 + 25

= -10 + 30

= 20.
