When 40 per cent of a number is added to another number the second number increases to its 140 per cent. What is the ratio between the first and the second number?
Choose one
A) 1 : 1	B) 4 : 3	C) 3 : 2	D) Data inadequate	E) None of these
Let the first and the second numbers be x and y respect then   y + 40% of x = 140% of y   or, y + 0.4x = 1.4y   or, 0.4x = 0.4y   ∴ x : y = 0.4 : 0.4 = 1 : 1   1 : 1nswer 1 : 1
