(#M40000163) GENERAL question Keep an EYE

A person wanted to withdraw X rupees and Y paise from the bank. But cashier made a mistake and gave him Y rupees and X paise. Neither the person nor the cashier noticed that.

After spending 20 paise, the person counts the money. And to his surprise, he has double the amount he wanted to withdraw.

Find X and Y. (1 Rupee = 100 Paise)

Solution

he wants to withdraw x rupee and y paise
but he obtained y rupee and x paise after spending 20 paise remaining amount = y rupee and (x-20) paise
it is given that y rupee (x-20) paise = 2(x rupee y paise)
on comparison we get y = 2x and x-20 = 2y but on solving we shall get x as a negative numbet which is a contradiction
an other case is also possible
y rupee (x-20) paise = 2(x rupee y paise)
so y rupee (x-20) paise = 2(x rupee) 2(y paise)
or y rupee (x-20) paise = (2x+1) rupee (2y-100) paise
y = 2x+1, x-20 = 2y-100
on taking y = 2x+1 in second equation, we get x-20 = 2(2x+1)-100
or x-20 = 4x+2-100 or 3x = 78 or x = 26, y = 53

X=26 Y=53. He wanted to withdraw 26 rupees 53 paise. But cashier gave 53 rupees 26 paise. He spent 20 paise. So remaining is 53 rupees 6 paise. It is double the amount he wanted to withdraw. 26.53 * 2 = 53.06.
