Math puzzle 1:
Tom, a salesman, sold twice as many pears in the afternoon as he did in the morning. If he sold 360 kg of pears that day, how many kg did he sell in the morning and how many kg in the afternoon?
Reply:
Tom sells 120kg in the morning and 240kg in the afternoon.
Explanation:
Suppose x is the number of kilograms he sold in the morning.
Next, in the afternoon he sold 2 kg.
Therefore, total x+2x=3x.
In this case, 3x= 360.
x= 360/3
x= 120
So in the morning Tom sold 120 kg.
2 multiplied by 120 is 240 kg. So in the afternoon he sold 240kg.
Math puzzle 2:
Julie has finished reading ⅔ of the book. She calculated that she had finished reading more than 90 pages. How long is her book?
Reply:
270 pages.
Explanation:
Assuming x is the total number of pages in the book, then she completes ⅔ multiplied by x pages.
Next, she has x-⅔ .x=⅓.x pages left.
⅔ . x – ⅓ . x = 90
⅓ . x = 90
x = 270
Math puzzle 3:
Rhea chose a number and divided it by 5. She then subtracted 154 from that result and got 6. Which number did Rhea choose?
Reply:
800
Explanation:
Next, let us assume x is the selected Rhea number
x/5 – 154 = 6
x/5 = 160
x= 800
So how many mistakes have you made? How many mistakes have you made?
