Ramu is 75% than gokul .if Ramu heightt increasess by 40% while gokul increases only by 25%, by what percent is Ramu taller than gokul now?
Read Solution (Total 6)
-
- If height of Gokul is x units, then
height of Ramu = 0.75x= 3x/4 units
After increase,
Height of Ramu = 1.4*3x/4 = 4.2x/4 = 2.1x/2 =1.05x
Height of Gokul = 1.25x
Diff in heights = 0.21x
Ramu is shorter than Gokul by 100*0.21x/1.25x = 21/1.25 = 16.8%

- suppose gokul's height is 100 cm
ramu's height will be 75 cm
now Ramu heightt increasess by 40%,means
75+((40*75)/100)=105 cm
now gokul increases only by 25%,so
it become 125 cm
percent is Ramu taller than gokul now is=((125-105)*100)/125=2000/125=16%(ans) - 12 years agoHelpfull: Yes(4) No(1)

If the question is Ramu's height is 75% more or 75% taller than Gokul.
Then if Gokul's height=1 , Ramu's height=1.75=7/4
40% increase in Ramu's height=1.4*7/4=2.45
25% increase in Gokul's height=1.25
% of Ramu's height to Gokul's height=(2.45/1.25)*100= 196 - 12 years agoHelpfull: Yes(2) No(2)
- If Gokul : 10
Ramu : 17.5
Ramu increases 40% , then 17.5+7=24.5,
Gokul increases 25% , then 10+2.5=12.5,
so Ramu is 49.5% is taller than Gokul. - 12 years agoHelpfull: Yes(0) No(1)
- Sorry , calculation is wrong
If Gokul : 10
Ramu : 17.5
Ramu increases 40% , then 17.5+7=24.5,
Gokul increases 25% , then 10+2.5=12.5,
so Ramu is 98% is taller than Gokul. - 12 years agoHelpfull: Yes(0) No(1)
