What is the value of x, if 25% of 480 + 30% of 500 + x% of 90 = 35% of 900?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 50
25% of 480 + 30% of 500 + x% of 90 = 35% of 900
⇒ (25/100) of 480 + (30/100) of 500 + (x/100) of 90 = (35/100) of 900
⇒ 120 + 150 + (9x/10) = 315
⇒ (9x/10) = 45
⇒ x = 50
