A) 12 B) 8
C) 6 D) 4
 
Answer & Explanation Answer: B) 8

Three-digit numbers: The three digits can be 1, 2 and 9 => 3! Or 6 possibilities.

We cannot have three digits as (3, 3, 2) as the digits have to be distinct.

We cannot have numbers with 4 digits or more without repeating the digits.

So, there are totally 8 numbers.

A) 74 units B) 92 units
C) 56 units D) 54 units
 
Answer & Explanation Answer: B) 92 units

Here given that sides a = 38, b= 36 and c = 18

solve_the_triangle_b36_a38_c181537423406.jpg image

 

Now, perimeter of the triangle = a + b + c = 38 + 36 + 18 = 92 units.
