Question

the ratio of the height of two sister is 7:8 if the height of shorter sister is 154 cm, what is the height of other sister?

Answer 1

Ratio is 7/8
Let height of other sister be x.
7/8=154/x
x=154*8/7
x=22*8
x=176

Answer 2

let the ratios of heights of both sister be

7x and 8x

given

height of shorter sister = 154 cm

we have

7x=154

x=154/7

x=22

therefore,

8x=8*22

. =176

therefore height of other sister =176cm
