Topic: Can someone try and solve this SHL question for me please

D ratio U supplied represents an everyday purchase ratio, Assuming today to be Tuesday, so we have Tuesdays purchase to be
T-0.04
C-0.06
A-0.50
R-0.20
L-0.15
O-0.05
All in %, sums up to 100%

Given relationships are:
1. T(Monday)= 1.07R(Sunday) 7% more Remember We assumed Today to be Tuesday, thus yesterday will be Monday, the day before being Sunday
2. R(Sunday)= 0.97C(Tuesday) 3% less
3. C(Tuesday)= 5kg

Find:
I) A(Monday)

Substitute C(Tuesday)= 5kg into the 2nd relationship i.e R(Sunday)= 0.97C(Tuesday)
therefore
R(Sunday)= 0.97(5kg)
R(Sunday)= 4.85kg

Solve for T(Monday) by substituting R(Sunday)=4.85kg into the 1st Relationship i.e T(Monday)= 1.07R(Sunday)
thus
T(Monday)= 1.07(4.85kg)
T(Monday)= 5.1895kg

We now have at least one concrete value for the quantity of Tomatoes bought for Yesterday(Monday), we can now use the ratio of daily purchase to find the quantity of any other item bought yesterday, in this case the Apples
Recall that:
T- 0.04% (4/100)
A- 0.50% (50/100)

to get the total quantity (X) of items bought yesterday would be;
4X/100 = 5.1895kg
cross-multiplying;
4X = 518.95kg
Solving for X (Making it the subject of the formular by dividing both sides by 4)
X = 129.74kg

Apple is 50% of X, thus
A= 0.5(129.74)
A= 64.87kg
The above is the quantity of Apples bought by John yesterday.

I took time to illustrate it all, in a normal test condition most of these steps can be solved visually, and everything taken care of under a minute, best of luck bro, keep preparing, the day of reward is sure coming, and our God who sees in the secret will reward U in the open

Triple C,

You're right. The key to solving such in a test is doing a visual. But then, you need to understand these steps to be able to do the visual check. Great way to go.

@Triple-C,

Mehn, you are a genius!!! Thanks.

@HigherHeights...U are right on point bro, one has to understand the steps and proceedures b4 raising the bar

@pein...brother no flatter me oh! Na God dey help each and every one of Us, especially me oh!
U're welcome man

This SHL people self!

The q is for ppl who can think.

Here’s an alternative presentation

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

no wonder u are called brainbox...guy U much oh!

Another genius in the house. Thanks Brainbox

pein...ur welcm bro,
triple-C..na u be bad guyz

@BrainBox...U wan shift the spotlight abi...lol, U don ever see where mechanical approach beat electrical? e no dey happen, b4 na cable, cable and more cables dey run our cars,but as brainbox come...LIFE BECAME AS EASY AS A B C.

brother finally, after U na still U!!! I gbadu d much guyz!!!
