shewolfangz Group Title

a triangle and a rectangle are drawn on a page so that they overlap as shown. inside these figures are placed the digits from 0 to 9. if there are six digits in the triangle and eight digits in the rectangle, how many digits are in the part that belongs to both figures

    six digits in the triangle-->Let T =6 eight digits in the rectangle---->Let R=8 Total = 10 digits. = T union R (in other words, T OR R) get this much ?

    0 to 9 means total 10 digits i assumed that the digits are not repeated, which is a fair assumption here...

    digits are in the part that belongs to "both" figures = T AND R (T intersection R) = ...... there is a formula for this, you know ? in terms of T,R and T UNION R

    now look at that figure, if u want total area of composite figure, will it be appropiate to add the area of triangle and rectangle ?

    by the area of composite figure do u mean the overlapped shape?

    yes,. because then you will consider the "intersection part" twice. once in rectangle and once in triangle, got this ?

    so to get area of composite figure, u need to subtract are of intersection, right ?

    so , we get TOTAL = RECT +TRIANGLE - INTERSECTION. in this case, total = 10 , Rect = 8, triangle =6 u just need intersection

    so, 10 = 8+6-x where x is digits that belongs to both figures
