In a primary school parents asked about of the number of hours they spend per day in helping their children to do home work. There were 90 parents who helped for frac(1)(2) hour to 1frac(1)(2) hours. The distribution of parents according to the time for which, they said they helped is given in the adjoining figure, 20% helped for the than 1frac(1)(2) hours per day, 30% helped for frac(1)(2) hour to 1 hours, 50% did not help at all. Using this, answer the following : How many said that they helped more than 1frac(1)(2) hours?
