1. Sumit and Amit undertook a work for Rs 7200. Sumit alone can do the work in 5 days and Amit alone can do the work in 4 days. If they work together, then what will be the difference (in Rs.) in the amount they receive?

Time taken by Sumit = 5 days and by Amit = 4 days Efficiency $$propto$$ $$frac{1}{time}$$ => Ratio of efficiency of Sumit and Amit = $$4:5$$ $$ herefore$$ Difference in amount that they will get = $$frac{(5-4)}{(5+4)} imes7200$$ = $$frac{7200}{9}=Rs.$$ $$800$$ => Ans - (A)
