If, + stands for division; × stands for addition; - stands for multiplication; ÷ stands for subtraction, which of the following equations is correct?
- a.$36+6-3\times5\div3=24$
- b.$36\times6+7\div2-6=20$
- c.$36\div6+3\times5-3=24$
- d.$36-6+3\times5\div3=74$
Answer: (D) $36-6+3\times5\div3=74$
Replace the signs as given: '+' is division, '×' is addition, '-' is multiplication and '÷' is subtraction. Option (D) becomes $36\times6\div3+5-3 = 72+5-3 = 74$, which is true. Option (A) gives $36\div6\times3+5-3 = 20$, not 24; option (C) gives $36-6\div3+5\times3 = 49$, not 24; and option (B) does not give a whole number.
