Answer:

here is your answer

Step-by-step explanation:

LET HEIGHT OF SANDY  BE X

HEIGHT OF SANDY AFTER 1  YEAR =X+{20X/100}=120X/100

HEIGHT OF SANDY AFTER 2 YEAR =120X+120X/100 *15/100=138X/100

THEREFORE INCREASE IN SANDY S HEIGHT IN 2 YEARS

={(HEIGHT AFTER 2 YEARS -HEIGHT BEFORE 2 YEARS)/HEIGHT  BEFORE 2 YEARS }*100

={(138X-X)/X}*100

=(38/100)*100=38 PERCENT
