There was a grandmother in a village who had a grandchild. Upon asking her grandchild's age she told dat she is as older as many days old as her daughter's age in weeks and as many days as her own age in years. The sum of the three is 130. then how old is the child?
a)7
b)8
c)6.5
d)7.5

Read Solution (Total 2)

Let the ages of grandmother, her daughter and the grandchild be x, y and z respectively in years.

z in days = y in weeks
z * 365 = y * 52 ... (i)

Similarly, z in days = x in years
z*365 = x ... (ii)

Also, x + y + z = 130 ... (iii)

Substituting the values of x, y and z in equation (iii) we get,

365*z + (365/52)*z + z = 130

Solving this we get z = 0.3485 in years = 127 days

So the child is 127 days old.

One friend suggests that they have a blindfold friend choose from well shuffled set of cards numbered one to six. You check and find that this method works as it should simulating a fair throw of a die. You check by performing multiple simultaneous trials of picking the cards blindfold and throwing a die. You note that the number shown by the method of picking up a card and throwing a real world die, sums to a number between 2 and 12. Which total would be likely to appear more often 8,9 or 10?
a) 8 b) All are equally likely c) 9 d) 10
