Doing the maths...... Help required (Solved 😁)

Right then - nothing to do with fintech really but I’m interested to know if this riddle can be solved using algebra or whether (don’t laugh) it’s trial and error. If it can, please someone - show me…

Simultaneous equations.

If s is the price of the shirt, s + 25 is the price of the jacket.

s + s + 25 = 87

2s = 87 - 25

s = 62 / 2

The shirt costs 31, the jacket costs 56.

And be careful about shopping there again. Not only are the prices opaque, but it’s not worth paying £31 for a shirt.

There it is.

Where I went wrong from the off was;

X+Y=85
X+25=Y

I had one variable too many…

You should take the rest of the day off …:grin:

You didn’t go wrong, you just stopped too soon.

X+(X+25)=85.

J = jacket cost
S = Shirt cost
S = 25 + J

S = J + 25
S + J = 87

(J + 25) + J = 87

2J + 25 = 87
2J = 62
J = 31

Yes… But where’s the fun in that :grin:?

Don’t forget to add the additional cost to the resulting division (at this stage if ‘J = jacket cost’, your workings are incorrect)

X=((87-25)/2)
J=X+25
