If the bonus figure is put as a part of cost to company as evidenced by a CTC structure in the in the contract of employment, then the employer should pay it to the employee. But in many cases, it would be put as payable 'depending on law in force'. Then it is disputable whether the amount is payable or not. The purpose of adding the amount of bonus to cost to company is to make it fancy and acceptable. But if the employer had expected that the amount shall vary depending upon the law regarding the minimum wages and the Payment of Bonus itself with regard to 'salary' restrictions like 7000 or minimum wages whichever is higher etc then, it can be considered as a flexible amount and is payable to those whose coming under the brackets only. But when the basic salary itself is more than Rs 21000, showing the amount of bonus as part of CTC will lead to make the employer pay the amount without doubt.
