john has rs 360 for his expenses . if he exceeds his days by 4 days he must cut down daily expenses by rs 3 . the number of days of john ' s tour program is
let john under takes a tour of x days . then , expenses for each day = 360 x 360 x + 4 = 360 x − 3 x = 20 and − 24 hence , x = 20 days . c
divide(subtract(sqrt(add(multiply(multiply(multiply(360, 4), 4), 3), power(multiply(3, 4), const_2))), multiply(3, 4)), multiply(const_2, 3))
