Solution

10% of x more than x = 1.1 x
20% of 2x less than 2x = 1.6 x
Therefore difference = 0.5 x
So % difference = 0.5x/ 1.6x * 100 = 500/16
= 31.25 %

SUNITEE GARIMA   9 years AGO

let x be 100.
A/q,
100+100*10/100=110
again,
2*100-200*20/100=160

160-110=50
50/160*100=31.25%

neha   9 years AGO

10% of x+x= 110*x/100
and 2x-20% of 2x=80*2x/100
160x/100-110x/100=50x/100
%=(50x/100)/(160x/100)*100=5*100/16=6.25*5=31.25% less

10% of x more than x= x+(10x/100) =11x/10
20% of 2x less than 2x =2x-(20*2x/100) =16x/10
req difference= 5x/10
req %age=(5x/10)*)100/16)*10=31.25%

kranthi kanchanapally   9 years AGO

clearly he has given x+10%(x) is what percent less than
2x-20%(2x)
then by solving we get
11x/10 , 16x/5
then 11x/10 is 31.25% less than 16x/5

2x - (2x*0.2) - (x + (x*0.1)) = 0.5x
Required Percentage =( 0.5x/2x - (2x*0.2))*100 = 31.25

anamika   9 years AGO

let x=100
and 2x= 200
then 80% of 2x= 160
and 110 % of x= 110
then ans = 50/160 *100= 31.25%

Rishabh Gupta   9 years AGO

x+x(10/100)=1.1x
2x-2x(20/100)=1.6x
now 1.1x is less by 0.5x than 1.6x
so 0.5x/1.6x=.3125 and so % is 31.25%.
