Question

Neeru height increased by 3 cm. If previous and increased height are in the ratio 36:37. Find present height​

Answer 1

Answer:

111cm

Step-by-step explanation:

precious and increaesd height in ratio 36:37

to be 36x and 37x and height increased by 3cm so,

37x- 36x = 3cm

x = 3cm

present height is 37x so,

37×3 = 111

Answer 2

Given :

• Neeru's height is increased by 3cm.
• The ratio of her previous and increased height is 36:37.

To Find :

• Present Height of Neeru.

Solution :

$\longmapsto\tt{Let\:previous\:height=x}$

$\longmapsto\tt{Present\:height=x+3}$

A.T.Q :

• The ratio of her previous and increased height is 36:37.

$\longmapsto\tt{\dfrac{x}{x+3}=\dfrac{36}{37}}$

$\longmapsto\tt{37(x)=36(x+3)}$

$\longmapsto\tt{37x=36x+108}$

$\longmapsto\tt{37x-36x=108}$

$\longmapsto\tt{1x=108}$

$\longmapsto\tt\bold{x=108}$

Value of x is 108 ..

Therefore :

$\longmapsto\tt{Present\:height=108+3}$

$\longmapsto\tt\bold{111cm}$

So , The present height of Neeru is 111cm.
