(iv) the total marks secured in all the three examinations.
(v) the total marks scored in all the three examinations.
(vi) her percentage score on the whole in all three examinations.

Answer 1

(i) `375/500xx100=75%`

(ii) `560/800xx100=70%`

(iii) `840/1200xx100=70%`

(iv) Total of maximum marks
= 500 + 800 + 1200
= 2500

(v) Total marks obtained in all the three term
= 375 + 560 + 840
= 1775

(vi) `1775/2500xx100=71%`
