Question 237

Nandita scored 80 per cent marks in five subjects together viz, Hindi, Science, Maths, English and Sanskrit together wherein the maximum marks of each subject were 105. How many marks did Nandita score in Science if she scored 89 marks in Hindi, 92 marks in Sanskrit, 98 marks in Maths and 81 marks in English?

Solution

The maximum marks of each subjec is 105

80% of 105 = 84

Since there are 5 subjects

Average marks =$$\frac{Sum\ of\ all\ the\ marks}{5} = 84$$

Sum of all the marks = 84*5 = 420

89+92+98+81+Science = 420

360+Science = 420

Science = 420-360 = 60
