At 5 p. m., Henry and Gordon have made 60 and 20 cranes respectively. Henry can make 30 cranes per hour while Gordon can make 40 cranes per hour. When will they get the same number of cranes?

9 p.m.

Step-by-step explanation:

Given:

To find:

Let the required time = x

For Henry:

For Gordon:

Since they require the same time and same number, we have:

The start time was 5 p.m., we need to add 4 hours to this to get 9 p.m.

At 9 p.m. they will get the same number of cranes

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.

the correct answer is d

hope this
