Neeru's height increased by 3cm. if the previous height and the increased height is in the ratio 36: 37. find her present height

Let us assume Neeru's present height = x cm.

After increasing height by 3 cm, new height = (x+3) cm.

Ratio of previous height and the increased height = 36:37.

Therefore,

On cross multiplication, we get

37x = 36(x+3)

37x = 36x + 108.

Subtracting 36 from both sides, we get

37x-36x  = 36x-36x + 108.

x = 108.

answer: d. $20

step-by-step explanation:

just took the test

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
