Donovan got 39 points out of 50 points.

Percentage marks that Donovan got =

=

If Marcis scored 10% more then his percentage of marks will be = 78 + 10 = 88%

Now we will calculate the marks Marcis obtained.

=

= 44

Marcis scored more than Donovan = 44 - 39 = 5

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
