DSSSB LDC Official Paper 1 (Held on : 18 Aug 2019 Shift 1)

## Solution:

Formula used:

Average = Sum of the marks/Numbers of Subject

Calculation:

Average marks = Sum of the marks/Numbers of Subject

⇒ Average marks = (80 + 90 + 70 + 84 + 86 + 92 + 88 + 81 + 99 + 97)/10

⇒ Average marks = 867/10 = 86.7

∴ The average marks obtained by students per subject is 86.7
