a train crosses a platform of 120 m in 15 sec , same train crosses another platform of length 180 m in 18 sec . then find the length of the train ?
"length of the train be ‘ x ’ x + 120 / 15 = x + 180 / 18 6 x + 720 = 5 x + 900 x = 180 m answer : option b"
subtract(multiply(180, divide(15, divide(15, const_3))), multiply(120, divide(18, divide(15, const_3))))
