Answer 1:

Tom, a salesman, sold twice as many pears in the afternoon. How many kilogrammes did he sell in the morning and afternoon if he sold 360 kilogrammes?

Answer:

Tom sold 120 and 240 kilogrammes.

Explanation:

Assume he sold x kg in the morning.

Afternoon, he sold 2kg.

x+2x=3x.

3x=360

x= 360/3

x= 120

That morning, Tom sold 120 kg.

2×120=240 kilogramme. That afternoon, he sold 240 kilogrammes.

Puzzle 2:

Julie read 2/3 of a book. She had 90 pages left to read. Book length?

Answer:

Pages: 270.

Explanation:

If the book has x pages, she finished 23 x.

x-23.x=13.x pages remain.

⅔ . x – ⅓ . x = 90

⅓ . x = 90

x = 270

Puzzle 3:

Rhea subtracted 5 from a number. After subtracting 154, she got 6. Rhea’s number?

Answer:

800

Explanation:

Assuming Rhea chose x,

x/5 – 154 = 6

x/5 = 160

x= 800
