Domestic LPG — household cooking gas supplied in cylinders — became costlier by Rs 50 each on Wednesday as state-run retailers passed on the impact of higher international benchmark rate. In the absence of subsidy, the fourth increase since March is bound to further stretch household budgets grappling with high motor fuel prices and last month’s imposition of GST on condiments and daily consumables. After the latest hike, a 14. 2kg refill will cost Rs 1,053 in Delhi, Rs 1,052 in Mumbai, Rs 1,079 in Kolkata and Rs 1,068 in Chennai. Rates will vary within this range in other states because of difference in local levies.
