A confused bank teller transposed the dollars and cents when he cashed a check for Ms Smith, giving her dollars instead of cents and cents instead of dollars. After buying a newspaper for 50 cents, Ms Smith noticed that she had left exactly three times as much as the original check. What was the amount of the check? (Note: 1 dollar = 100 cents.)
18.56 $
ReplyDelete$ 18.56 is the amount on check
ReplyDeleteyes kamal u r right
ReplyDeleteAmol Sir, how do we proceed for this one?
ReplyDeleteActually, I assumed original amount to be x dollars and y cents.
And then got the equation as:
100y+(x-50)=3(100x+y)
Multiplied by 100 as 1 dollar equals to 100 cents. Then unable to procedd furthur :(.
