Question 190100
4/15 of the 315 members of the book club are male.How many female members are there in the club?
A:84
B:131
C:174
D:231

>>> We have a total of 315 members, out of which 4/15 are male. thus the number of male members out of 315 will be:

{{{ (4/15)*315 = 84 }}} members
Remaining members are female, which are {{{ 315 - 84 = 231 }}} members.

so choice (D) is correct.

and my other question is
A chef prepared five chocolate tortes for a dinner party.The guests consumed 2 5/16 tortes.How many tortes are let?
A:2 11/16
B:3 11/16
C:2 9/16
D:3 9/16

>>> total chocolate tortes prepared = 5.
The guests consumed {{{ 2 + 5/16 }}} tortes =  {{{ 37/16 }}} tortes.
so tortes left will be:

{{{ 5 - 37/16 = 43/16 = 2 + 11/16}}} tortes.

So choice (A) is correct.

Hope this helps.
