C. 49 D. 55
Read Solution (Total 8)
-
- let the no. be 3x n 5x
then ATQ, (3x-9):(5x-9)=12:23
now solve 4 x, x=11
now smallest no. is 3x ,i.e., 3*11=33. ans - 9 years agoHelpfull: Yes(8) No(0)
- x:y=3:5
(x-9):(y-9)=12:23
solve above eqns., x=33 and y=55
smallest number is 33 - 12 years agoHelpfull: Yes(5) No(3)
- 3x,5x
3x-9,5x-9
(3x-9)/(5x-9)=12/23
x=11
so 3x=33,5x=55
Ans:33 - 10 years agoHelpfull: Yes(1) No(0)
- 33
i dont know - 12 years agoHelpfull: Yes(0) No(0)
- Ans. is 33
- 9 years agoHelpfull: Yes(0) No(0)
- x/y=3/5
x-9/y-9=12/23
by solving these two answer will be 55 and 33 - 9 years agoHelpfull: Yes(0) No(0)
- 33:55
3:5
33-9=24; 55-9=46
24:46
12:23
ANSWER 33 - 8 years agoHelpfull: Yes(0) No(0)
- let numbers be 3k,5k
3k-9/5k-9=12/23
k=11
3k=3*11=33
ans B.33 - 7 years agoHelpfull: Yes(0) No(0)
