If 90 is increased by x%, then it becomes 117. What is the value of x?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 30.
Explanation:
According to the given question;
⇒ 90 × (100 + x)/100 = 117
⇒ 100 + x = 130
⇒ x = 130 - 100
⇒ x = 30
Hence the required value of x is 30.
