- 100y+x-5 = 2(100x+y)
solve for diff values of x & y from options - 13 years agoHelpfull: Yes(6) No(4)
- he gets 100y+x paise instead of 100x+y paise
(100y+x) - (100x+y) - 5 = (100x+y)
99y -99x - 5 = 100x + y
98y = 199x + 5
y = 2x + (3x+5)/98
only an integer value of x = 31
will make y an integer
with the constraints that both x & y < 100
substituing, y = 2*31 + 1 = 63
ans: 31 rs 63 paise - 13 years agoHelpfull: Yes(5) No(4)
