Correct option is D
Logic: interchange mathematical operators and solve as per BODMAS rule.
Operation preference wiseBracketsOrders,ofDivisionMultiplicationAdditionSubtractionSymbol[],,()(power),√(root),of÷×+−
Check option A,÷ and ×
Given:
48÷16×24-5+3=12
After interchanging,
48×16÷24-5+3=12
32-5+3=12
30≠12
So, its not correct option.
Check option B, ÷ and +
Given:
48÷16×24-5+3=12
After interchanging,
48+16×24-5÷3=12
Here, 5 is perfectly not divisible by 3.
So, its not correct option.
Check option C,− and ÷
Given:
48÷16×24-5+3=12
After interchanging,
48-16×24÷5+3=12
Here, 24 is perfectly not divisible by 5.
So, its not correct option.
Check option D,+ and ×
Given:
48÷16×24-5+3=12
After interchanging,
48÷16+24-5×3=12
3+24-15=12
12=12
So, its correct option.
Thus, correct option is (d).
