The value of 15 x 8 - 20 is:

• a.80
• b.100✓
• c.140
• d.120

15 x 8 = 120; 120 - 20 = 100.

If x + 7 = 20, then x equals:

• a.13✓
• b.14
• c.27
• d.10

x = 20 - 7 = 13.

The area of a rectangle 12 cm by 5 cm is:

• a.120 sq cm

A number increased by 25% becomes 250. The original number is:

• a.187.5

1.25x = 250, so x = 200.
