Lot u g assun-æ that t he amount Ryan to withdraw i g 4 digit number
Also, let u be the digit in the place, b the hundreds p!aee, e in the tens d in
the r.meß place. So, the a.moun.t he had to = IOOOÆ + 100b -F IOC -+- d.
Note, Ryan wrote the last two digits in place of the first two digits, and first two digiis in place
of the Iasi two digits in the cheque.
In other words, he wrote c in the thousands place, d in the hundreds place, a in the tens Nace
and b in the ones place. So, the amount he actually withdrew IOCOc + I Ood + I Oa — b.
Now, Ryan brought a 5 regres pouch tÜith the withdrawn money. So, the amount now ft with
him = IOfId | h 5.
n now reuli sed that the aduac' amount he should have written in the cheque is iwice the
amount left with him.
. + 100b + + d = 2(1000c + 100d + + b — 5)
10000 + 100b + + d = 20DOc + 200d + 20u + 2b
980u 98 - 1990c — 109d + 10
98(10a + b) - + d)
The abote equation is satisfied u'
So, the amount Ryan withdrew
3673
10 0
3, and d 6.
1000c + + + b + 600 + 70 3
