Answers
Given : correctly attempted 18 questions and got 110 marks.
. Questions were of two types. Type A awarded 10 marks and Type B awarded 3 marks to him.
To Find : total marks of another lot of 18 questions in which number of correctly attempted Type A and Type B are interchanged
Solution:
Type A = x
Type B = 18 - x
Type A Marks = 10x
Type B Marks = 3(18 - x) = 54 - 3x
10x + 54 - 3x = 110
=> 7x = 56
=> x = 8
Type A = 8
Type B = 10
Interchanged
Type A =10
Type B = 8
Marks = 10 (10) + 3(8)
= 100 + 24
= 124
