Isn't the price somewhat arbitrary? WhatsApp's market value is based not on revenue but on what the highest bidder will give them. WhatsApp probably had an idea of what the big players (Apple, Google, Facebook) might offer and that becomes what their going rate is. I don't know if this is how the amount of an offer is determined but it sounds plausible to me.
