Question

In a game Malini scored 20, −40, 10 , -5 and Meera scored – 40, 10, 20 , -8.

Who scored more and by how much? (please give the whole explaination)​

Answer 1

Answer:

ஃ Malini's score is greater than Meera's score by 3 points.

Step-by-step explanation:

i) Malini's score = 20 + ( -40 ) + 10 + ( -5 )

= ( -40 ) + ( -5 ) + 20 + 10

= ( -45 ) + 30 = -15

ii) Meera's score = ( -40 ) + 10 + 20 + ( -8 )

= ( -40 ) + ( -8 ) + 10 + 20

= ( -48 ) + 30 = -18

-15 > -18 = Malini > Meera

Difference = ( -15 ) - ( -18 )

= ( -15 ) + 18 = 3
