if A:B = 2:3, B:C = 4:5, then C:A=?
A:B:C = 2:3
4:5 (LCM of 3 and 4 is 12, because here B has 2 values)
=(2:3) x 4 & (4:5) x 3
= 8 : 12
12:15
so, A:B:C = 8:12:15
but question is to find C:A = 15:8
therefore answer is option (A)
A:B:C = 2:3
4:5 (LCM of 3 and 4 is 12, because here B has 2 values)
=(2:3) x 4 & (4:5) x 3
= 8 : 12
12:15
so, A:B:C = 8:12:15
but question is to find C:A = 15:8
therefore answer is option (A)
