@JS-M said: richie, a bar musician was broke so he sold his guitar for $144 and earned as much profit % as was the CP of the guitar in dollars. After few months, when he had the money he brought the guitar back at discount in dollars (on earlier SP) equal to half of his profit % in earlier transaction. By what % was the second CP more than the first CP?a.4b.24c.30d.40
Answer shud be 8% more..Those whu have a diff answer plz explain...
My Explanation:
Cp initially rs 80 and profit % was 80 so SP=144
Now he bought it at 40%(half) discount on 144 which is 57.6 and after deucting it from
144=>144-57.6=86.4
Now the % by which the second CP more than the first CP= (86.4-80)/80 *100=8%
Plz explain ur approach as this is not in the option...

bhai usme bataya na 40 dollar minus karna hai % nhi
aur 193 kaise aya yaar tumhara vo bhi explain kar do
aur 193 kaise aya yaar tumhara vo bhi explain kar do
@watsnew24 said:bhai usme bataya na 40 dollar minus karna hai % nhiaur 193 kaise aya yaar tumhara vo bhi explain kar do
Bhai 52*85-47*83=519
Now 80+81+82+83=326
Subtract 326 from 519 to get 193 the answer....
@sscjindabad said:watsnew plz explain
yaar N divided by M rem = 11 & 8M = 92
so Mk + 11 = N (k a variable) same 8Ml + 92 = N(l also a variable
solve karne pe M(k-8l) = 81 ayega
ab take M = 81 k = 9 & l = 1 it would satisfy this solution
put values & get answer
