Answer:
option a
Step-by-step explanation:
let cp be x
therefore,
sp, if its sold at 5% profit,
sp= cp+ 5% of cp
sp= x+ 5x/100
sp=21x/20
sp, if it's sold at 10% profit
sp= cp+ 10% of cp
sp= x+ 10x/100
sp=11x/10
a/c we can say,
11x/10 = 21x/20 +1000
11x/10 - 21x/20 = 1000
x/20 = 1000
x= rs. 20000 ans.
