BENGALURU, Nov 1 (Reuters) - Home appliances maker Whirlpool of India WHIR.NS reported a 39% drop in second-quarter profit on Tuesday, as costs increased and demand for white goods was muted amid surging inflation. It had booked a one-time fair value gain of 3.25 billion rupees last year on equity interest in kitchen appliances maker Elica India. Under pressure from higher commodity costs, household appliance makers like Whirlpool and IFB Industries IFBI.NS, resorted to price increases, but that ended up curbing demand at a time when consumers are stretched thin.
