Let T, R & C represent Tomatoes, Radishes and Cucumbers respectively

Quant of C (today)=5kg

Quant of R (day before yesterday) is 3% less quant of C above = 0.97×5 = 4.85kg

Quant of T (yesterday) is 7% greater than quant of R above = 1.07×4.85 = 5.19kg

Ratio of tomatoes to apples for ANY given day is 4:50 or alternatively 1:25, wch means for every kg of tomatoes purchased, jhn also bought 12.5kg of apples.
So if john bought 5.19kg of Tomatoes yesterday, he also bought (5.19×12.5)kg of apples = 64.875kg

The key is having a very clear understanding of what is requested of you, and quickly isolating relevant information (in the right order).

Hope this helps too

Brainbox well done. TrippleC you try too. Just wanted to point out that in gmat/shl each question is expected to be solved in about a minute & hopefully without a calculator. So any solution that appears to be a long thing then u know're you're on a wrong track. Some questions don't even need solving just reasoning things out from answer options available and picking the correct answer. So it this case brainbox's solution is the way u're supposed to handle it on the battle field. As others have said u need to understand the question well and experience has shown that practice makes perfect. By the time you run through many of such questions in ur leisure u'll be over confident and easily decipher tough nuts on test day.

SHL QUESTION:

John buys everyday 4% tomatoes, 6% cucumbers, 50% apples, 20% radishes, 15% lemons and 5% oranges. If the quantity of tomatoes bought yesterday is 7% more than the quantity of radishes bought the day before yesterday, which is 3% less than the quantity of cucumbers bought today, which is 5 kilograms, what is the quantity of apples bought by John yesterday?
SOLUTION:

Let m = quantity of cucumbers bought today;

∴x = 5kg
Let y = quantity of radishes bought the day before yesterday;

∴ y = 3% less than x;
⇒ (100% - 3%) of x;
= 97% of x;
=[IMG]file:///C:/Users/HILARY%7E1/AppData/Local/Temp/msohtmlclip1/01/clip_image002.gif[/IMG]× x;
= 0.97 × 5;
= 4.85kg
Let z = quantity of tomatoes bought yesterday;
∴ z = 7% more than y;
= (100% + 7%) of y;
= 107% of y;
=[IMG]file:///C:/Users/HILARY%7E1/AppData/Local/Temp/msohtmlclip1/01/clip_image004.gif[/IMG]× 4.85;
= 1.07 × 4.85;
= 5.1895kg;
This clearly represents 4% of the total quantity of fruits and vegetables bought yesterday, since 4% of tomatoes are usually bought daily by John.
Let m = total quantity of vegetables and fruits bought yesterday;
∴ z = 4% of m;
⇒ 5.1895 = [IMG]file:///C:/Users/HILARY%7E1/AppData/Local/Temp/msohtmlclip1/01/clip_image006.gif[/IMG]× m;
5.1895 = 0.04 × m;
∴ m = [IMG]file:///C:/Users/HILARY%7E1/AppData/Local/Temp/msohtmlclip1/01/clip_image008.gif[/IMG];
= 129.7375kg
A little consideration upon the question will show that 50% apples are bought daily, and this represents 50% of the total quantity of fruits and vegetables bought daily as well.

Hence, for John’s yesterday’s purchases;
Let a = quantity of apples bought yesterday;

∴ a = 50% of the total quantity of fruits and vegetables bought yesterday;
= 50% of m;
= [IMG]file:///C:/Users/HILARY%7E1/AppData/Local/Temp/msohtmlclip1/01/clip_image010.gif[/IMG]× 129.7375;
= 64.86875kg;
≈ 65kg (answer)

I hope you understood the solution vividly and without a single hitch, because I took my time to prepare it.
But SHL self! I think that the question difficulty level was too high within the time frame of the test… you do not think so?
