If m × 7 + 4 − 6 ÷ 3 − 7 + 45 ÷ 5 × 4 + 49 = 87, then the value of m is:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1.
According to the given question,
m × 7 + 4 − 6 ÷ 3 − 7 + 45 ÷ 5 × 4 + 49 = 87
Applying the rule of BODMAS,
⇒ m × 7 + 4 − 2 − 7 + 9 × 4 + 49 = 87
⇒ 7m + 4 − 2 − 7 + 36 + 49 = 87
⇒ 7m + 4 - 9 + 85 = 87
⇒ 7m + 80 = 87
⇒ 7m = 7
⇒ m = 1
Hence the required answer is 1.
