Question

ravishing bought 100 article for ₹4000.he sold 20 of them at a gain of 5% at what gain % must he sell the article so as to gain 20% at whole? ​

Answer 1

$<b><u>$ Hello,
Here is the solution ❤️❤️

CP for 100 articles = 4000
Cp of 1 article = 4000/100 = 40

Cp for 20 article = 20×40 = 800

SP at 5% gain

= 5%of 800+800
= 40+800
=840₹

CP for remaining articles = 80×40=3200

Profit at whole = 20%

Total CP =4000
Total SP ==> [20/100 × 4000] +4000

==> 800+4000

==> 4800₹

Sp for remaining articles ⤵️⤵️
=4800-840
=3960

Profit on 80 articles = 3960- 3200
==>760

P% ==> p/CP ×100
% ==> 760/3200×100
%==> 23.75ans.

Answer 2

SOLUTION___(. ❛ ᴗ ❛.)

Given, Ravish bought 100 article for Rs.4000

then, Cost price of 1article= 4000/100

Cost Price= 40Rupees

He sells 20 articles at gain 5%

so,

Selling price of 20 articles= 40×20+40×20×5/100

= 800+40= 840rupees.

and whole of 20% profit

So, profit wants = 20/100×4000

= 800rupees

Cost Price of 80 articles= 80×40

= 3200rupees

from Rs.800 he already got profit of Rupees 40 rhen ge gets more Rs.760

Profit%= p/cp×100

= 760/3200×100

= 23.75% ans.
