. What must be added to the two numbers, which are in ratio 5 : 12, so that the new ratio
becomes 3:4?
(a) 5 (b) 8 (c) 1 2 (d) 1 6
Read Solution (Total 11)
-
- (d) 16
let x be reqd no. then
A/Q
(5+x)/(12+x) = 3/4
=> 20+4x = 36+3x
=> x = 16 - 10 years agoHelpfull: Yes(28) No(1)
- 16
trial and error method
from the options 16 is the suitable ans... - 9 years agoHelpfull: Yes(4) No(0)
- 5+x/12+x = 3/4
20+4x = 36+3x
x= 16 - 10 years agoHelpfull: Yes(2) No(0)
- let the added number be x,then
5+x/21+x =3/4
then x=16 - 9 years agoHelpfull: Yes(2) No(0)
- 16 i s the ans
- 9 years agoHelpfull: Yes(1) No(0)
- let x be added so (5+x)/(12+x)=3/4
or,x=16 - 9 years agoHelpfull: Yes(1) No(0)
- ans--16
5+16=21
12+16=28
hence 21/28 =3/4 - 8 years agoHelpfull: Yes(1) No(0)
- how could be the ratio equal to number??
- 9 years agoHelpfull: Yes(0) No(0)
- 5+16=21
16+12=28
21:28=3:4 - 9 years agoHelpfull: Yes(0) No(0)
- 5+x/12+x=3/4
4(5+x)=3(12+x)
20+4x=36+3x
x=16 - 8 years agoHelpfull: Yes(0) No(0)
- (5+x)/(12+x) = 3/4
=> 20+4x = 36+3x
=> x = 16
- 8 years agoHelpfull: Yes(0) No(0)
