The H.C.F and L.C.M of two numbers are 84 and 21 respectively. If the ratio of the two numbers is 1:4, then the larger of the two numbers is: Choose the most appropriate option:	A) 12	B) 24	C) 84	D) 48	E) 42
Let the numbers be x and 4x. Then, x * 4x = 84 * 21 x2 = (84 * 21)/4 = x = 21.   Hence, larger number = 4x = 84.   ANSWER:84
