a person saved $ 10 in buying an item on sale. if he spent $ 200 for the item, approximately how much percent he saved in the transaction?
add(floor(multiply(divide(10, add(10, 200)), const_100)), const_1)
"actual price = 200 + 10 = $ 210 saving = 10 / 210 * 100 = 100 / 21 = 5 % approximately answer is d"
