Step-by-step explanation:
Given वर्गों 90–120 और 120–150 के वर्ग चिन्हों का योग है:
- Now we need to find the sum of mark of the class.
- Now the mark of the class 90 – 120 will be
- Upper class limit = 120 and lower class limit = 90
- Now mark of the class is given by upper limit + lower limit / 2
- = 120 + 90 / 2
- = 210 / 2
- = 105
- Similarly for the class interval 120 – 150 we get
- upper class limit = 150 and lower class limit = 120
- The mark of class 120 – 150 = upper limit + lower limit / 2
- = 150 + 120 / 2
- = 270 / 2
- = 135
- Therefore sum of the two will be 135 + 105 = 240
