Which of the following equation has ‘5’ as solution ? A) x – 5

1.	Which of the following equation has ‘5’ as solution ? A) x – 5 = 1 B) 10x = 50 C) bx = 2 D) 50x = 5
Answer» Correct option is B) 10x = 50 Correct option is (B) 10x = 50 (A) x – 5 = 1 \(\Rightarrow\) x = 1 - (-5) = 1+5 = 6 (B) 10x = 50 \(\Rightarrow\) \(x=\frac{50}{10}=5\) (C) bx = 2 \(\Rightarrow\) \(x=\frac2b\) (D) 50x = 5 \(\Rightarrow\) \(x=\frac{5}{50}=\frac1{10}.\)

Which of the following equation has ‘5’ as solution ? A) x – 5 = 1 B) 10x = 50 C) bx = 2 D) 50x = 5

Answer»

Correct option is B) 10x = 50

Correct option is (B) 10x = 50

(A) x – 5 = 1 \(\Rightarrow\) x = 1 - (-5) = 1+5 = 6

(B) 10x = 50 \(\Rightarrow\) \(x=\frac{50}{10}=5\)

(D) 50x = 5 \(\Rightarrow\) \(x=\frac{5}{50}=\frac1{10}.\)
