using Nrf240L1 single master receiver and two slave transmitter

Can you help me in coding of Single master and dual slave using nrf240L1 communication , two nrf slaves will send transmiit random data to single master continously and master will shoild receive data simultaneously.

Have a look at this Simple nRF24L01+ Tutorial. It includes an example with a master and 2 slaves.

It is quite impossible for the master to receive two messages simultaneously because it only has one wireless receiver. However messages take very little time so receiving one message after the other is likely to be near enough to simultaneous.
