(With full explanation)... ​

Answer 1

Answer:

2000 is the answer...

Step-by-step explanation:

when the trader marked the watch 40% above the cost

then

(40% = 0.4,,,,10%=0.1)

ORIGINAL + (0.4*original) = real cost

1.4ORIGINAL = real cost

then he gave 10% discount on the marked price.

10% of 1.4 is 0.14

1.4 -- 0.14 = 1.26

now come to the second section

trader earned 468 after paying 10% tax on profit

which means

profit - (0.1*profit) =468

0.9 profit =468

profit = 468/0.9 = 520

so that means 0.26 of original price is 520

then

0.26 of original is 520

then 520/0.26

is 2000....

which is the answer...
