To do :
We have to find,
(i) In which subject, has the child improved his performance the most?
(ii) In which subject is the improvement the least?
(iii) Has the performance gone down in any subject?
Solution :
% change in marks in English $= \frac{(70-67)}{67} \times 100% =\frac{3}{67} \times100%=4.47$%
% change in marks in Hindi $= \frac{(72-65)}{72} \times 100% = \frac{7}{72} \times 100% = 9.72$%
% change in marks in Maths $= \frac{(95-88)}{88} \times 100% = \frac{7}{88} \times 100% = 7.95$%
% change in marks in Science $= \frac{(85-81)}{81}\times100%= \frac{4}{81} \times 100% = 4.94$%
% change in marks in S.Science $= \frac{(75-73)}{73} \times 100% = \frac{2}{73}\times100% = 2.74$%
(a) The child improved his performance most in the subject in which there is an increase in marks and greater improvement in the percentage
The child improved his performance the most in Maths(7.95%).
(b) The child improved his performance least in the subject in which there is an increase in marks and least improvement in the percentage
