Question

Payal was 120cm tall last year, but now she is 132cm tall. Express her growth in percentage. If she continues this percentage of growth, how tall will she be next year?​

Answer 1

Answer:

10%

Step-by-step explanation:

growth is 132 - 120 = 12

in percentage is 12/120×100=10%

Answer 2

Payal's height last year =120 cm

Payal's height this year =132 cm

Height that has increased in one year :-

$= 132 - 120$

$= 12 \: cm$

Thus Payal's height increased = 12 cm

Percentage of increase :-

$= \frac{12}{120} \times 100$

$= \frac{1200}{120}$

$= \frac{120}{12}$

$= 10\%$

Thus percentage of growth in Payal's height =10%

Payal's height next year :-

$= 132 + 12$

$= 144 \: cm$

Thus, Payal's height next year =144 cm

Therefore, percentage of growth in Payal's age =10% and her height next year =144 cm .
