Question

Neeraj height increased by 3 CM if the previous and the increase height are in the ratio of 36 to 37 find the present height​

Answer 1

Answer: 111 cm

Explanation:

Given that ratio of previous and height increase is ;

36 : 37 - - - - (1)

Height increase = 3cm

Therefore,

Assume current height = x

Previous height = x - 3

Proportion of current and previous height ;

(x - 3) / x - - - - (2)

Equating both equations (1) and (2);

36 / 37 = (x - 3) / x

Cross multiply

36x = 37(x - 3)

36x = 37x - 111

36x - 37x = - 111

-x = - 111

Divide both sides by - 1

x = 111cm

Therefore, present height = 111

Prevuous height (x - 3) = (111 - 3) = 108cm
