certain article. If the cost price of the article is 1500rupees, what is the printed price? 0237
(1) * 1680 (2) 1850 (3) 2200 (4) 2250
​

Answer 1

Answer:

cp=1500

d%=20%

p%=20%

mp=x(let)

finding sp:

if cp=100 then sp=120

if cp = 1 then sp = 120/100

if cp = 1500 then sp =(120*1500)/100

= 1800

now,

sp=mp-d% of mp

1800=x-(20/100)*x

1800= x-x/5

1800*5 = 4x

x=Rs.2250 Ans
