7. Neeru's height increased by 3 cm. If the previous and the increased height are in the ratio 36:37, find her present height​

Answer 1

Step-by-step explanation:

Let the previous height be x cm. Then, the present height will be x+3 cm.

Given, ratio =36:37=x:(x+3)

36/37=x/(x+3)

36(x+3)=37x (by cross-multiplying)

36x+108=37x

37x-36x=108

x=108=her previous height

x+3=111=her presnt height
