The ratio of boys to girls in a group is 4:1. If there are 33 more boys than girls, work out how many people there are in total.
MissTica

Total number of people is 55

<u>Step-by-step explanation:</u>

Step 1:

Given ratio between boys and girls is 4:1. Let number of girls be x, so number of boys = 33 + x

⇒ 4x + x = x + 33 + x

⇒ 5x = 33 + 2x

⇒ 3x = 33

⇒ x = 11

Step 2:

Find total number of people.

33 + 2x = 33 + 22 = 55

Raphael is timing how fast he can do a series of 5
Nana76 [90]

Answer:

Time left for each question is less than 5.5 minutes

Step-by-step explanation:

Given that:

Raphael is trying to solve 5 math questions in less than 20 minutes.

3 questions have been completed which have taken 3 minutes each.

To find:

How much time is left with Raphael for each question so as to reach his goal.

Solution:

First of all, let us find the time that has been already consumed by Raphael in solving the 3 questions.

3 \times 3 = 9 minutes

Time left = Total Time - Time already consumed

Time left = 20 - 9 = 11 minutes

Number of questions to be solved = Total questions - Questions solved

Number of questions to be solved = 5 - 3 = 2

Average time left for each question = Time left divided by Number of questions to be solved

Average time left for each question = 11 \div 2 = 5.5 minutes

Therefore, time left for each question is less than 5.5 minutes.
