neha scored 75% in science,95% in maths and 70% in english. If the max. marks in these subjects were 80,100and 70,respectively. find her aggregate percentage.

80 * 75 % = 80 * 75 / 100 = 6000 / 100 = 60
100 * 95 % = 100 * 95 / 100 = 9500 / 100 = 95
70 * 70 % = 70 * 70 / 100 = 49
[ ( 60 + 95 + 49 ) / ( 80 + 100 + 70 ) ] * 100 % =
( 204 / 250 ) * 100 % = 0.816 * 100 % = 81.6 %
