Step-by-step explanation:26 trees have 25 gaps between them
225/25=9
apples cost = 15
Cost of 120 apple = 120/15
= 8
Total marks of 5 students = 5 × 18 = 90
Total marks of 6 students = 6 × 19 = 114
Marks of the sixth student = 114 - 90 = 24
The total marks of 5 boys is 36 * 5 = 180.
When the sixth boy's marks are included, the total becomes 32 * 6 = 192.
The sixth boy's marks are 192 - 180 = 12.
To find the average:
First 5 multiples of 11:
11, 22, 33, 44, 55
Add the multiples:
11 + 22 + 33 + 44 + 55 = 165
Divide by the number of multiples:
165 ÷ 5 = 33
The average of 50 numbers is 30, so the sum of all 50 numbers is 50 x 30 = 1500.
If we discard 35 and 40, we subtract these from the total sum: 1500 - 35 - 40 = 1425.
Now, we have 48 numbers left (50 - 2 = 48).
To find the new average, we divide the remaining sum by the number of remaining numbers: 1425 ÷ 48 ≈ 29.68.
So, the correct answer is: 29.68
