1) Relax
2) Stop, Breathe
3) Think throug each problem ONE STEP AT A TIME.
4) WRITE DOWN more than you think you need.

Let's try the first one.

Rule #1 - Name Stuff

Reading the problem, we're going to need to know the price of Apples and the Price of Bananas and the Price of Pears.

A = Price of 1 Apple
B = Price of 1 Banana
P = Price of 1 Pear

That's it!

"Five apples and six bananas together cost as much as 8 bananas and 9 pears"

5A + 5B = 8B + 9P

"one apple cost as much as 2 pears "

A = 2P

"for the same price as 1 pear, how many bananas could be bought?"

P = xB

Your task is to solve for x.

Let's see what you get.

Solution for problem #3
So, this looks pretty straight forward. Just add all those 8 numbers and you will get 12345686. Then when you look at the hundred part you see 686, meaning there are 6 hundreds and the answer is G.

Solution to problem #4
4.Mario, John and Boris are teenagers and the sum of their ages now is 49. the sum of their ages 8 years from now will be F, and the sum of their ages 10 years was P. The value of F-P is.

Are you sure the question is written correctly? Or should say and the sum of their ages 10 years ago was P?

I am pretty sure there is some key word missing in this question.

Otherwise, if you assume that it says 10 years from now then P = 30 (3 x 10), F = 24 (3 x 8), but then if you calculate F-P = 24 - 30 = -6, and there is no such answer.

Just a Social Note. What you have stated is EXACTLY what a cheater would say. SHOW YOUR WORK! No one can help you if no one ever sees you DO anything.
