Question

the hight of a child increases in the ratio 2:3. the hight at present is 140 c m . what is the new hight ​

Answer 1

Step-by-step explanation:

2 x + 3x = 140 \\ 5x = 140 \\ x = 140/5

$2 x + 3x = 140 \\ 5x = 140 \\ x = 140/5 \\ x = 24 \\ \\ 2x = 24 \times 2 \\ \\ = 48$

$= 48 \\ 3x = 24 \times 3 \\ = 72$
