See 1 Answer

Valerie originally has 40% more than
isabelle,

If isabelle is 100 then Valerie was 140

Now

Valerie bough 25 more means

11.25 x 140 = 175% of isabelle original

Then isabelle gave away is 75% of original

Therefore 225% of isabelle

Total book /225 x 140 = Valerie book

I don't understand how you get 11.25
If I use 750÷225×140 = 466.666 but answer should be 420

It did help me in understanding that both V & I have 100% as 1u though. Anyway thanks

Valerie = 100%+40%+25% = 175%
Isabelle = 100%-25% = 75%

175%+75%=250
250%=750
1%=750÷250=3
140×3=420

Sorry

Ethan you are correct

Now I learnt from you

11.25 is a mistake

Should be 1.25, even that I thought wrongly
