Lower Secondary Mathematics

you can try the casco mathematics tutor, though is for express students. but the difference between express & NA is just that NA takes a longer time to finish the topics.

ultimately, they take the same O level paper.

Mr Tan’s monthly savings (S) is directly proportional to the square root of his monthly income (I). His income in January and February 2011 is $3600 and $2500 respectively. His savings in January is $80 more than in February. Find the amount he saved in January 2011.

S ∝ √I

S=k√I

January's savings ,
S(J)=k√3600 =60k

February's savings,
S(F)=k√2500 =50k

His savings in January is $80 more than in February,

S(J) - S(F) = 80
60k - 50k = 80
10k = 80
k = 8

S = 8√I

S(J) = 8√3600 = 480

the amount he saved in January 2011 is $480
