D. None of these
Suppose amount of cake=100
Father took = 1/4 * 100 = 25
Suppose amount of cake=100
Father took = 1/4 * 100 = 25
Remaining = 100 -25 = 75
Let the number of people = x
Distribution to the family members = 75(remaining amount of cake) / x (number of family members)
Its given father had 3 times as much as each of the other members had,
Therefore, 25(Father’s amount of cake) = 3 times as much as each of the other members (75/x)
then, 25= 3 * (75/x)
x=9
Total= 9 +1(Father)=10 family members.
Why x+1 ? Why not only x ?
No explanation of calculation.
