The Lok Sabha and Rajya Sabha seats in Haryana are:

Concept: Under the Constitution, each state's Lok Sabha seat count is fixed by delimitation based on population (frozen since the 1971 census by the 42nd/84th Amendments, pending the next delimitation), while its Rajya Sabha seat count is fixed under the Fourth Schedule, also roughly proportional to population, out of a national total of 245 Rajya Sabha seats.

Application: Applying this allocation to Haryana, the state currently sends 10 members to the Lok Sabha and 5 members to the Rajya Sabha, giving the pair "10 and 5".

Cross-check: This total of 15 parliamentary seats for Haryana is consistent with its share of the country's population under the frozen delimitation, and no other listed pairing reproduces both figures together:

• "7 and 4" understates both the Lok Sabha figure (10) and the Rajya Sabha figure (5).

• "10 and 4" gets the Lok Sabha figure right (10) but understates the Rajya Sabha figure, which is 5, not 4.

• "12 and 5" gets the Rajya Sabha figure right (5) but overstates the Lok Sabha figure, which is 10, not 12.
