Kamlesh - what you have there is a Cattleya alliance hybrid orchid. With the hybrids it is almost impossible to identify them because so many look alike. Basic care for your plant would be bright light, no direct sun, water heavily (you want water gushing out of the bottom of the pot) and don't water again until the potting medium is completely dry. Fertilize weekly during the growing season with a balanced fertilizer at 1/4 to 1/2 strength.
