If 30 + 180 ÷ 30 × 6 − 15 − 16 − 60 ÷ n − 15 = 0 , then the value of n is:
Show answer & explanation
Correct answer: C
Explanation
The Correct answer is option 1 i.e. 3
Given that
If 30 + 180 ÷ 30 × 6 − 15 − 16 − 60 ÷ n − 15 = 0
⇒ 30 + 180 ÷ 30 × 6 − 15 − 16 − 60 ÷ n − 15 = 0
⇒ 30 + 6 × 6 − 15 − 16 − 60/n − 15 = 0
⇒ 30 + 36 - 46 - 60/n = 0
⇒ 66 - 46 = 60/n
⇒ 20 = 60/n
⇒ n =60/20 = 3
