mr yadav spends 60 % of his monthly salary on consumable items and 50 % of the remaining on clothes and transport. he saves the remaining amount. if his savings at the end of the year were 38400, how much amount per month would he have spent on clothes and transport?
multiply(divide(divide(38400, divide(divide(multiply(subtract(const_100, 60), 50), const_100), const_100)), multiply(const_3, const_4)), divide(divide(multiply(subtract(const_100, 60), 50), const_100), const_100))
"∵ amount , he have spent in 1 month on clothes transport = amount spent on saving per month ∵ amount , spent on clothes and transport = 38400 ⁄ 12 = 3200 answer c"
