Question 1

(a). Evaluate, without using mathematical tables or calculator,

(3.69 x 105) /  (1.64 x 10-3), leaving your answer in the
standard form.

(b). A man invested N20,000 in bank A and N25,000 in bank B at the beginning of a year.  Bank A pays simple interest at a rate
of y% per annum and B pays 1.5% per annum.  If his total interest at the end of the year from the two banks was N4,600, find the value of y.

Observation

Many candidates performed poorly in the (a) part on simple numerical exercise.  They evaluated the division using calculators when the rubrics of the question stated otherwise.  This cost them some marks.

Majority of the candidates had unsatisfactory presentations in the (b) part.  They were expected to use the simple interest relation
{  I   =   PRT }  to solve the problem.
{           100 }

 

Interest in A   =  20,000  x y  x  1    =   200y
                                       100
Interest in  B   =  25,000  x  1.5y  x  1    =    375y
                                       100

          Total interest  =  200y  +  375y  =  4600
                                                575y   =  4600
                                                      y   =  4600     =    8.
                                                                575
