Question

There were five sections in MAT paper. The average score of Pooja in first 3 sections was 83 and the average in the last 3 sections was 97 and the average of all the sections (i.e., whole paper ) was 92, then her score in the third section was

Answer 1

Answer:

80

Step-by-step explanation:

first 3 sections = a + b + c = 83 * 3 = 249

last 3 sections = c + d + e = 97 * 3 = 291

overall = a + b + c + d + e = 92 * 5 = 460

therefore,

third section score = (a+b+c)+(c+d+e)-(a+b+c +d+e)

= 249 + 291 - 460

= 540 - 460

= 80
