If (x - 2)/3 = (x + 4)/5 then what is the correct value of x?

यदि (x - 2)/3 = (x + 4)/5 हो तो x का सही मान क्या है?

A 9 / 9 B 10 / 10 C 11 / 11 D 12 / 12
Show answer and explanation
Correct Answer

C. 11 / 11

Explanation

Cross multiplication gives 5x - 10 = 3x + 12 so 2x = 22 and x = 11.

क्रॉस गुणा करने पर 5x - 10 = 3x + 12 इसलिए 2x = 22 और x = 11।
