If a exceeds B by 40% and B is less than C by 20% then A:c=
a.3:1
b.3:2
c.26:25
d.28:25
Read Solution (Total 2)
-
- Let B=1 then A = 1.4
Let C=x, as per question B is less than C by 20% it implies 80% c is B
so 80/100 * C = B
4/5 *C =1
c= 5/4=1.25
A:c = 1.4/(5/4)
= 14*4 / (10*5)
= 28:25 - 10 years agoHelpfull: Yes(2) No(0)
- A=(140/100)B
again, B=(80/100)C,
then, A=(140*80)/(100*100)C
So, A:C= 28:25 - 9 years agoHelpfull: Yes(1) No(0)
