A man divides his property so that his son’s share to his wife’s and the wife’s share to his daughter are both in the ratio 3 : 1. If the daughter gets 10,000 less than the son, find the total worth of the property. | [
"16,500",
"15,300",

] | C | Let Son’s share = S;
Daughter’s share = D;
and Wife’s share = W.
Also, S : W = W : D = 3 : 1
∴ S : W : D = 9 : 3 : 1
then S = 9x , D = x
and 9x – x = 10,000 ⇒ x = 1250
∴ Total worth of the property = (9 + 3 + 1)x = 13x
= 13 × 1250 = 16,250

In a graduating class of 234 students, 144 took geometry and 119 took biology. What is the difference between the greatest possible number and the smallest possible number of students that could have taken both geometry and biology? | [
"115",
"88",
"144",

Smallest Possible Number taken both should be given by
Total - Neither = A + B - Both
Both = A+B+Neither - Total (Neither must be 0 to minimize the both)
So 144 + 119 + 0 - 234 = 29
Greatest - Smallest is 144-29 = 115
