Question

There are following denominations of money: 1, 2, 5, 10, 20, 50, and 100 paise. Alex has as twice money as David, who has as twice as Bindya, who again has as twice money as Charles. Each has two coins in hand. Which coins Bindya has?

Answer 1

Let Charlie has X money
Then, Bindya has 2X money
David has 2(2X) = 4X money
and Alex has 2(4X) = 8X money

we get, Alex : Bindya : David : Alex = 1 : 2 : 4 : 8

A/C to question,
each has two coins in hand

if we give 10 and 5 paise coins to Charlie
then , Charlie has 15 paise {10pasie, 5 paise }
so, Bindya has 30 paise {10 paise, 20paise }
David has 60 pasie {10 paise, 50 paise }
Alex has 120 paise { 20 pasie , 120 paise}

so, Bindya has 10 paise and 20 paise
