I think that Q16 is 23
Q16 is 24 and not 23. Lim Min and Lim Jeck have checked this question. Current age of Father=60, Mother=52, Helen=28, John=24, Lucy=22.
Lim Li
why mother=52 not 51
The question said that the current average age of the family, excluding Helen is 39.5 years old. If the mother is 51 and John is 23, then the current average age excluding Helen would be 39 years old instead which is wrong. So 51 is wrong.

hi afternoon ,How much marks to get gold for nmos this year
Hi, for Question 4, the answer should be 108.
As for Question 7, the answer should be 25.
Lastly, Question 17 I got a fraction so as the examiner said to round off if there are any answers with decimals, hence the answer I got was 42.

Yes, you are right about Qn 7. I have changed the answer to 25.
For Qn 4 and 17, our original answers are correct.
I think for Qn 4, you failed to consider that the horizontal row and vertical row may be switched as well, hence X2.
For Qn 17, the answer is a whole number. How do you even get a decimal?!
LM
ok, thanks a lot.
