To fence the 25 feet long side, required number of pillars = (25÷5) + 1 = 6
To fence the 40 feet long side, required number of pillars = (40÷5) + 1 = 9
To fence the 55 feet long side, required number of pillars = (55÷5) + 1 = 12
As the plot is triangular and each of the two sides have a common vertex, total number of pillars needed = (6+9+12) – (1×3) = 24.
Answer: 24 pillars.

In the class of 78 students, there are four groups of students:
i. Taking both French and German = 9 students (given)
ii. Taking only French = 41-9 = 32
iii. Taking only German = 22-9 = 13
iv. Taking neither French nor German = x.
So, x+9+32+13 = 78

The average age of 12 children = 15 years.
So, the total age of 12 children = 15×12 = 180 years.
After the new children comes,
The average age of 12+1 = 13 children = 14 years.
So, the total age of 13 children = 14×13 = 182 year.s

27^(-1/3)n = 243
=> 27^(-n/3) = 243
=> 3^3(-n/3) = 3^5
=> 3(-n/3) = 5
=> -n = 5
=> n = -5.
Answer: (-5).
35-E: If 16+4x is 10 more than 14, what is the value of 8x?
==>
16+4x is 10 more than 14
=> (16+4x) – 14 = 10
=> 16+4x-14 = 10
=> 4x = 10-2
=> 4x = 8
=> x = 2.
So, 8x = 8×2 = 16
