given,
3a/ ( a-2b ) = 2 = 6 /3
so, 3a = 6 .... a = 2
and a - 2b = 3
2-2b= 3
-2b = 1
b= -1/2
substituting the values of a and b in the comparison we get,
A = 4a-2b / ( a-2b) = ( 4x2 - (2x -1/2) )/ 3 = ( 8 +1) / 3 = 3
and
B = a + 4b = 2 + (4 x (-1/2) ) = 2 -2 = 0
Hence A > B ( option A)
3a/ ( a-2b ) = 2 = 6 /3
so, 3a = 6 .... a = 2
and a - 2b = 3
2-2b= 3
-2b = 1
b= -1/2
substituting the values of a and b in the comparison we get,
A = 4a-2b / ( a-2b) = ( 4x2 - (2x -1/2) )/ 3 = ( 8 +1) / 3 = 3
and
B = a + 4b = 2 + (4 x (-1/2) ) = 2 -2 = 0
Hence A > B ( option A)
