Director's Message
Dear Students/Parents
APEX INSTITUTE has been established with sincere and positive resolve to do something rewarding for
ENGG. / PRE-MEDICAL aspirants. For this the APEX INSTITUTE has been instituted to provide a

JEE / PRE-MEDICAL exams. In fact, as question patterns are changing, now you need to have a different
approach for these exams. As far as ENGG. / PRE-MEDICAL preparations is concerned, students have
been wasting time and energy, studying Physics, Chemistry and Maths at different places. At APEX
INSTITUTE, the scope of the subject has been deliberately made all- inclusive to free them of this
burden. APEX INSTITUTE offers you complete preparation for IIT-JEE/PRE-MED. exams under one
roof.
Grooming at the APEX INSTITUTE is done methodically focusing on understanding of the subject,

(b) Divide 36 into four parts so that if 2 is added to the first part, 2 is subtracted from the second
part, the third part is multiplied by 2, and the fourth part is divided by 2, then the resulting
number is the same in each case. [5]
17. (a) The heights of the boys in cm of a class are given below. If the mean height is 152.2 cm.
Find the value of p. [5]
