Here is the answer :-

Given ,

Papaya tree was planted two years ago , and its growing rate is 20% .

Present height of tree = 540 cm

Height before 1 year = 20% of 540 cm

=> 20/100 × 540

=> 2 × 54

=> 108

➡️ (540 - 108) cm

=> 432 cm

Height before 2 years ago = 20% of 432 cm

=> 20/100 × 432

=> 86.4 cm

➡️ (432 - 86.4) cm

=> 345.6 cm

$\boxed {Answer\;=\;345.6cm}$

Hope it will be helpful..✌️✌️✌️
