Answer 1

Answer:

Let x be the boys full growth;

78% of x = 130 cm

solution:

x × (78/100) = 130

78x = 130 × 100

x = 13000 ÷ 78

x =166.67 cm

therefore, the full height which the boy will eventually reach at the end of growth period is 166.67cm

Answer 2

Answer:

Explanation:

Let x be the boys full growth;

78% of x = 125 cm

solution:

x × (78/100) = 125

78x = 125 × 100

x = 12500 ÷ 78

x = 160.25 cm

therefore, the full height which the boy will eventually reach at the end of growth period is 160.25 cm
