A casino has $10, $25, $50, and $100 chips. If a player wants to bet $165, what is the least number of chips he must use?

A. 5
B. 6
C. 7
D. 8
E. 10


At first subtract the only term containing 5 i.e. 25, then to make the remaining 140 by minimum possible means we need 1* 100 + 4*10.
Hence total no of bets = 1+4+1=6

The Only chip containing 5 is 25. Hence this chip must occur odd number of times.

Better to subtract the value of one chip and then play with numbers.

165-25 = 140.

140 = (100*1 + 10*4) = 5 chips or 140 = (50*2 + 10*4 ) = 6 chips or 140= (25*4 + 10*4) = 8 chips

Best option is 6 chips - (5 chips for totalling $140 and 1 - 25$ chip)

Hi!
The quant question in "GMAT Club Question Of The Day Email service" is redirecting me to this particular question only. I see E-mail contains different question (mostly by math revolution) daily, but when I click the answer explanation link, I land here.
Thanks! :)

If and are positive integers, is a^2 - b^2 divisible by 5?

(1) 2ab is divisible by 5
(2) a - b is divisible by 5



This was part of question of the day with the question being (a^2 + b^2) instead of (-). Can you share the answer for this question. I thought that it was C
