Answer»

Let the apple be denoted as 'x' and mangoes be denoted by 'y'. And the money he carrying be 'm'

Now, man can purchase 16x=10y=m

A/c to the statement, he bought 4x+5y=m-204*(m/16)+5*(m/10)=m-20m/4+m/2=m-208m-6m=160m=80 Rupees

Therefore, for apples 16x=mi.e. x=80/16One apple cost x=5 Rs.

Similarly for mangoes 10y=mi.e. 10y=80Price of 1 mango is y=8 Rs.

And the difference between them is Rs: 3
