Rohan sold a calculator to Vishal at 20 percent profit Vishal sold it to Naresh at 5% profit if Naresh paid 441 it what was the cost price of the calculator
Answers
Let, the initial C.P. be,'x'
20% of x = 20x/100
So, Vishal paid for it = (x+20x/100)
= (100x+20x)/100
= 120x/100
5% of 120x/100 = (120x/100)*(5/100)
= 120x*5/100*100
= 600x/10000
So, Naresh paid for it = (600x/10000)+(120x/100)
= (600x+12000x)/10000
= 12600x/10000
By condition,
12600x/10000=441
or, x = 441*100/126
or, x = 441*50/63
or, x =7*50
or, x = 350
(Ans): rs.350
Answer:
350
Step-by-step explanation:
let cost of calculator be = 100k
Rohan sold a calculator to Vishal at 20 percent profit
vishal paid = 100k +100k[20/100]
=100k +20k
=120 k
Vishal sold it to Naresh at 5% profit
Naresh paid = 120k + 120k[5/100]
= 120k +6k
=126k
but he paid 441
126k = 441
k =441/126
cost of calculator be = 100k =44100/126
=350
