Answer 1

Answer:

28 plants in Garden

2 /7 have thorns in their stems.

How many do not have thorns?

• Let's Head to the Question Now :

⇒ Have Thorns = Total × 2 /7

⇒ Have Thorns = 28 × 2 /7

⇒ Have Thorns = 4 × 2

⇒ Have Thorns = 8

• Plants without thorns in their stem :

⇒ Do Not Have Thorns = Total Plants – Have Thorns

⇒ Do Not Have Thorns = 28 - 8

⇒ Do Not Have Thorns = 20

∴ Plants without thorns in stems are 20.

_________________________________

• Shortcut Trick :

⇒ Do Not Have Thorns = Total × (1 - 2/7)

⇒ Do Not Have Thorns = 28 × (7 - 2) /7

⇒ Do Not Have Thorns = 28 × 5 /7

⇒ Do Not Have Thorns = 4 × 5

⇒ Do Not Have Thorns = 20

∴ Plants without thorns in stems are 20.
