Correct Answer: 3.5

Explanation:

Let the number is = x

(89)² + x² = 16202

x² = 8281

x = 91

=> (1/26) of 91 = 3.5

Correct Answer: 14.9985

Explanation:

Given exp =  18225 10 2 + 18225 10 4 + 18225 10 6 + 18225 10 8

 

               =  18225 10 + 18225 10 2 + 18225 10 3 + 18225 10 4

 

               =  135 10 + 135 100 + 135 1000 + 135 10000

 

               = 13.5+1.35+0.135+0.0135=14.9985

Correct Answer: 12

Explanation:

Let  x 128 = 162 x

 

Then,  $$\begin{gathered} x 2 = 128 × 162 = 64 × 2 × 18 × 9 \\ = 8 2 × 6 2 × 3 2 = 8 × 6 × 3 = 144 \end{gathered}$$

 

? x = 12
