Correct option is A
Given:
5 + 3 × 12 ÷ 12 - 4 = 12
Solution:
As per the question interchanging the sings + and × we get,
5 × 3 + 12 ÷ 12 - 4 = 12
using BODMAS rule – brackets (), {}, [], after that (powers, root) ans then symbols- first solve division, multiplication, sum, and at last subtraction
when division solve , we get = 5 × 3 + 1 - 4 = 12
Now solve multiplying, we get = 15 + 1 - 4 = 12
Now solve addition, we get = 16 - 4 = 12
Now solve subtraction, we get = 12 = 12
At finally, 12 = 1 2
final answer we got is + and ×.
trick to solve;
interchanging the sings + and × we get,
5 × 3 + 12 ÷ 12 - 4 = 12
5 × 3 + 1 - 4 = 12
15 + 1 - 4 = 12
16 - 4 = 12
12 = 12
