A son brought his old father to a restaurant for dinner. The father, who was very old and weak, dropped food on his shirt and pants while eating. Other guests looked with disgust at his son’s silence.

After he finished eating, his son who was not at all embarrassed, quietly took him to the washroom, wiped the food particles, removed the stains, combed his hair and fitted his spectacles firmly. When they went out, she looked at the entire restaurant in silence, not understanding how someone could embarrass herself in public. The son paid the bill and left with his father.

At that time, an old man amongst the diners called out to the son and asked him, “Don’t you think you have left something behind?”.

The son replied, “No sir, I haven’t”.

The old man retorted, “Yes, you have! You left a lesson for every son and hope for every father”.

The restaurant went silent.

**Correct answer**

**The correct answer is A: 61.**

Why is that?

Well, first of all, we have to start by solving the multiplication, 60 x 0, which will be 0.

So this leaves us with 60 + 0 + 1 and so, it becomes quite easy to see that the correct answer is 61.

But if you forget you must always start with the multiplication, then it gets tricky!
