Is it a rounded number? Why? I got 24% by calculating the full formulas given in intro.

Here's my guess and I'm not sure if this actually makes sense. RMS = MS_company / MS_nice_travel for each company. Then RMS * MS_nice_travel = MS_company for each company. We can take MS_travel_co divided by the sum of RMS * MS_nice_travel for each company. You can organize like this:

MS_travel_co = (0.6 * MS_nice_travel) ÷ ((0.2 + 0.3 + 0.4 + 0.6 + 1) * MS_nice_travel)

This answer calculates to 0.24

Yeah I think there’s something wrong with it

Looking for case interview partners in Singapore

The step by step approach is by referring to the ratios given.

Travelco/Nice = 0.6

Nice/Travelco = 1.7

Super/Nice = 0.3

Flamingo/Nice = 0.4

Cool/Nice = 0.2

Then, from the x axis, we know Nice + Super + Travelco + Flamingo + Cool = 150.

Just by doing math manipulations, we can obtain Nice = 60; then Travelco is 0.6 X Nice, which is 36. Finally, Travelco market share = 36/150 = 24%.

Btw, may I know where I can get the this full case? I looks interesting. :)

Express every individual company market share as a function of NiceTravel’s market share (using RMS), then setup an equation to solve for Nice Travels market share (40%). From there onwards, use the expression for Travel Co market share relative to Nice Travel to solve for Travel Co market share.

Thus = 24%

To the answers received so far: what's the number 1 you are adding in the denominator?

Because we want to compare that with the nice travel, so let’s say Cool=0.2*nice travel, and Flamingo=0.3*nice travel, but nice travel is not 1.7*nice travel
