Select the correct sequence of mathematical signs that can sequentially replace the * signs and balance the given equation.
6 * 10 * 55 * 162 * 9 = 23
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ×, −, +, ÷
Using the BODMAS rule we get:
6 × 10 – 55 + 162 ÷ 9 = 23
6 × 10 – 55 + 18 = 23
60 – 55 + 18 = 23
5 + 18 = 23
23 = 23
As we get the option 1 correct so there is no need to check other options as we have already got the correct answer.
