Question

A Giant Redwood Tree is x m tall. It grows by 5% and then by 8% to reach
a height of 22.68 m. Find x

Answer 1

||✪✪ GIVEN ✪✪||

• Height of Giant Redwood Tree = x m.
• First Time Growth = 5% .
• Second Time Growth = 8%

|| ✰✰ ANSWER ✰✰ ||

Given That , The Tree Grows 5% in First Team.

So, it will become =

→ x + (5% of x )

→ x + (5 * x/100)

→ x + (x/20)

→ (21x/20) m.

________________________

Now, Height of Tree is (21x/20) m , and It Grows 8 % Again, and Reached to a Height of 22.68m.

So,

→ (21x/20) + [8% of (21x/20)] = 22.68

→ (21x/20) + [ (8 * 21x) / (100*20) ] = 22.68

→ (21x/20) + (21x/250) =22.68

→(21x*25 + 21x*2) / 500 = 22.68

→ (525x + 42x) = 22.68 * 500

→ 567x = 11340

→ X = 20m.

Hence, Height of Giant Redwood Tree is 20 m.

Answer 2

Hence the value of x= 20 m
