Question

0.3x. + 0.4 = 0.28x + 1.16, x = ………………………… 

A) 10 

B) 38 

C) 19 

D) 29

Answer 1

Correct option is  B) 38

Answer 2

Correct option is (B) 38

0.3x. + 0.4 = 0.28x + 1.16

\(\Rightarrow\) 0.3x - 0.28x = 1.16 - 0.4

\(\Rightarrow\) 0.02x = 0.76

\(\Rightarrow\) \(x=\frac{0.76}{0.02}=\frac{76}{2}=38.\)
