Question

Can anyone solve this question and for a student of level of 10th standard?
a+b+c+d=63
then find maximum value of ab+bc+cd?​

Answer 1

Step-by-step explanation:

a=d=1, as a and d are used only once in the calculations.

max values of b and c will be 31 and 30 in any order.

so

ab + bc+ ad = 1×31+31×30+30×1=31+930+30

= 991
